Science Newsletter of the Faculty fo Physics
This is a new bulletin, which, as we hope, will bring fresh, updated information on scientific news, research activities, and related events in the life of our department to our staff members, undegraduate and graduate students, postdocs, collaborators and partners. We greatly hope that this Science Newsletter will help us to find new partners in research and shorten the way from fundamental research to applications and innovations, from our fundamental discoveries to their successful implementations in not too distant future.
XIV National School-Seminar "Wave phenomena in inhomogeneous media"
The conference papers from the School-Seminar «Waves-2014» will be submitted for publishing in the Memoirs of the Faculty of Physics journal.

1.- Moscow state university of radio engineering, electronics and automation.78 Vernadsky prosp.,Moscow, 119454, Russia. 2.- Wave research center of the A.M.Prokhorov General physics institute RAS. 38 Vavilov str., Moscow, 119991, Russia. 3.- Institute of Electronics, Microelectronics and Nanotechnology (IEMN UMR CNRS 8520) PRES Lille North of France, ECLille, B.P. 48, 59651 Villeneuve d'Ascq Cedex, France.The cascade process of generation of the second acoustic harmonics accompanied by its simultaneous parametric wave phase conjugation in α-Fe2O3 antiferromagnetic crystal under transversal electromagnetic field is studied experimentally and theoretically. The necessary conditions for generation at variations of the magnetization direction relatively to the crystallographic axes and direction of propagation of transversal sound wave are defined. The observed effect is caused by the magnetoelastic interaction and is described in the framework of the theory of giant effective elastic anharmonicity.
