TRIBUTE TO PROFESSOR L. A. SHUVALOV

L. ERIC CROSS Materials Research Laboratory, The Pennsylvania State University, University

Park, PA 16802 USA

It is a signal honor and real privilege to have this opportunity to pay tribute to the outstanding work of Professor L. A. Shuvalov in the field of ferroelectric and ferroelastic crystals. Having been in this field myself since early in 1949, I have been continually impressed by the steady stream of seminal papers from the Moscow Institute of Crystallography authored by Lev Shuvalov and his co-workers. Lev has made fundamental contributions to the discussion of the basic crystallography of ferroelectricity, the interpretation of the symmetry changes in ferroelectric and ferromagnetic phase transitions, the general group theoretical classification of fer- roelectrics and of the attendant domain structures and domain properties. These topics have been brilliantly elucidated and the understanding deeply enriched by these original works so that they have now become an integral part of the basic understanding of the subject. For those like myself, who attempt to teach the symmetry properties of ferroelectrics and the logical classification of prototypic and domain state properties, the “capstone” paper presented by Lev Shuvalov on this subject at IMF2 in Kyoto is a continuing source of information and inspiration.

In more detailed studies one must recognize the early works on the optical rotating properties of some ferroelectric crystals and the role of this chiral behavior, the detailed studies of domain phenomena, and the elegant technique for revealing domains using liquid crystal coatings. More recently, the focus by Shuvalov and co-workers upon ferroelasticity resulted in the discovery of the first proper fer- roelastic potassium trihydrogen selanate [KH3(Se03)*], elucidation of the domain structures and switching properties of a number of ferroelastics and of the domain contributions to internal friction in these crystals.

Continuously, with his major role as a researcher in ferroelectricity, Professor Shuvalov has been always active as an organizer and facilitator for national and international conferences and seminars on ferroelectricity . As a member repre- senting the USSR on the Advisory Committee for the International Meeting, he has been a steady advocate for the best interests of the international community. In the USA we have been aware for some years of the highly successful joint USSR:Japan seminars on ferroelectricity which Lev helped to facilitate. This year for the first time, we ourselves were able to enjoy a somewhat similar meeting in Boulder, Colorado, and look forward, with help from Professor Shuvalov and colleagues, to continuing dialogue in ferroelectricity .

Professor Shuvalov has served with distinction on the editorial boards of the journals FERROELECTRIC, FERROELECTRIC LETTERS, and ZEIT- SCHRIFT FUR KRISTALLOGRAPHIC. No tribute to Lev would however be complete, fitting, or proper without comment upon his bluff, but most engaging, personality. It is always a real pleasure to be in personal contact, to feel the stimulation of a sharp mind, but also the evident deep concern for basic human needs and the strong sense of humour that leavens the more serious moments.
