The Lecture Notes in PhysicsThe series Lecture Notes in Physics (LNP), founded in 1969, reports new developmentsin physics research and teaching – quickly and informally, but with a high quality andthe explicit aim to summarize and communicate current knowledge in an accessible way.Books published in this series are conceived as bridging material between advanced grad-uate textbooks and the forefront of research to serve the following purposes:• to be a compact and modern up-to-date source of reference on a well-defined topic;• to serve as an accessible introduction to the field to postgraduate students and nonspe-cialist researchers from related areas;• to be a source of advanced teaching material for specialized seminars, courses andschools.Both monographs and multi-author volumes will be considered for publication. Editedvolumes should, however, consist of a very limited number of contributions only. Pro-ceedings will not be considered for LNP.

Volumes published in LNP are disseminated both in print and in electronic formats,the electronic archive is available at springerlink.com. The series content is indexed,abstracted and referenced by many abstracting and information services, bibliographicnetworks, subscription agencies, library networks, and consortia.

Proposals should be sent to a member of the Editorial Board, or directly to the managingeditor at Springer:

Preface

This book is a collection of scientific articles on current developments of NMRand ESR techniques and their applications in physics and chemistry. It isdedicated to Professor Robert Blinc, on the occasion of his seventieth birthday,in appreciation of his remarkable scientific accomplishments in the NMR ofcondensed matter. He is a physicist commanding deep respect and affectionfrom those who had the opportunity to work with him.

Robert Blinc was born on October 31, 1933, in Ljubljana, Slovenia. Hegraduated in 1958 and completed his Ph.D in 1959 in physics at the Univer-sity of Ljubljana. His doctoral research on proton tunneling in ferroelectricswith short hydrogen bonds was supervised by Professor Dusan Hadzi. Aftera postdoctoral year spent in the group of Professor John Waugh at M.I.T.,Cambridge, Mass., Robert Blinc was appointed as a professor of physics at theUniversity of Ljubljana at a time when there was scarce research in the fieldof condensed matter in Slovenia. With his far-sighted mind, Robert Blinc,together with Ivan Zupancic, started the NMR laboratory at the Jozef Ste-fan Institute in Ljubljana. He immediately realized the enormous potentialof NMR methods in the research of structure, dynamics, and phase tran-sitions in solids. In the subsequent years he made significant contributionsin applying magnetic resonance to the research of ice, ferroelectric materi-als, liquid crystals, incommensurate systems, spin glasses, relaxors, fullerenes,and fullerene nanomagnets. His work led to the detailed understanding ofthe microscopic nature and properties of those materials. To mention only afew: Robert Blinc and coworkers elucidated the isotopic effect in ferroelec-tric crystals, predicted the Goldstone mode in ferroelectric liquid crystals,studied the impact of collective orientational fluctuations on spin relaxation,detected solitons and phasons in incommensurate systems using NMR, anddetermined the Edwards-Anderson order parameter in glasses and relaxors.He also pioneered the application of NMR to the nondestructive oil-contentmeasurements in seeds and the development of the NMR measurements ofthe self-diffusion coefficient in broad-line materials. In the early stage of thedouble resonance technique, he succeeded in obtaining the first nitrogen NMR

VIII Preface

spectra in nucleic acids and peptides. An important achievement of ProfessorRobert Blinc, which attracted considerable attention in the broad scientificcommunity, is the book Soft Modes in Ferroelectrics and Antiferroelectrics(North Holland), written by him and Bostjan Zeks in 1974. The book wastranslated into Russian (1975) and Chinese (1982) and belongs to the 600most-cited scientific books in the world. Another of his books, written to-gether with Igor Musevic and Bostjan Zeks, The Physics of Ferroelectric andAntiferroelectric Liquid Crystals, was published by World Scientific in 2000.

Apart from being professor of physics at the University of Ljubljana, thehead of the Condensed Matter Physics Department at Jozef Stefan Instituteand a member (and vice-president in the years 1980–1999) of Academy ofScience and Arts of Slovenia, Robert Blinc maintained a wide range of contactswith scientists worldwide. There is an amazingly long list of his internationalscientific activities. To mention only a few of them, he was a visiting professorat the University of Washington in Seattle; ETH Zurich; Federal Universityof Minas Gerais in Belo Horizonte, Brazil; University of Vienna in Austria;University of Utah in Salt Lake City; Kent State University in Ohio, ArgonNational Laboratory, and several others. In the years 1988–1994 he was thepresident of the Groupement AMPERE (Atomes et Molecules Par EtudesRadio Electrique), and president of the European Steering Committee onFerroelectrics (1990–1999). He is a member of seven foreign Academies ofSciences and has received several national and international scientific prizesand medals.

As the head of the Condensed Matter Physics Department at the JozefStefan Institute for more than 40 years, Robert Blinc promoted, in addition toNMR, other experimental techniques: ESR, dielectric measurements, opticalspectroscopy. He also atomic force microscopy. He also took active part insolving theoretical problems related to the systems under study. He was thesupervisor of 67 diploma works and 35 Ph. D. theses in the field of condensedmatter physics in Ljubljana. He can therefore be recognized as the founderand tireless promoter of the condensed matter physics research in Slovenia.

Most of Robert Blinc’s research is tightly related to nuclear magnetic res-onance. Therefore we invited a number of prominent researchers in this fieldto write chapters on the recent condensed matter physics research based onnew NMR and ESR techniques. The book covers:

• Adiabatic and nonadiabatic magnetization caused by rotation of solidswith dipole-dipole coupled spins.

• Magnetic resonance techniques for studying spin-to-spin pair correlationin multi-spin systems.

• Studies of selectively deuterated semisolid materials and anisotropic liquidsby deuterium NMR.

• Initial steps toward quantum computing with electron and nuclear spinsin crystalline solids.

Preface IX

• Laser radiation-induced increase of the spin polarization in various mag-netic resonance experiments.

• Multiple-photon processes in cw and pulse electron paramagnetice reso-nance spectroscopy.

• NMR and EPR for the determination of ion localization and charge trans-fer in metallo-endofullerenes.

• NMR shifts in metal nanoparticles of silver, platinum, and rhodium.• NMR relaxation studies of different superconducting systems.• Investigations of static and dynamic properties of low dimensional mag-

netic systems by NMR.• NMR-NQR relaxation studies of spin fluctuations in two-dimensional

quantum Heisenberg antiferromagnets.• The dynamics of the deuteron glass in KDP type crystals studied by var-

ious one-dimensional and two-dimensional NMR techniques.• Nuclear Magnetic Resonance cryoporometry based on depression of the

melting temperature of liquids confined in pores.

We congratulate Professor Robert Blinc on his great scientific achieve-ments and also express our deep gratitude for his continuous efforts in stim-ulating and supporting the NMR and condensed matter physics community.
