THE INFLUENCE OF CANTED MAGNETIC SUBARRAY ON THE SPECTRUM OF SPIN WAVE IN A CRYSTAL ^{[№ 10 ' 2004]}
The influence of canted magnetic subarray on the spectrum of spin wave in a crystal was searched in this article. The calculations indicated that record of canted magnetic moments can lead in some cases to large changes of spin wave spectrum, which was connected with existence of strong exchange interaction of magnetic moments in these crystals.

SPIN-WAVE DYNAMICS OF PHASE TRANFORMATION VTSP IN MAGNETOCERAMIC SYSTEMS ^{[№ 6 ' 2004]}
The electron-phonon interaction exchange amplification effect in complicated connections of rare-earth metals and ceramic metal-oxide systems with the perofskite structure was examined by means of Puasson brackets. A dispersion equation was obtained and an effective parameter of the spin-phonon connection was found. The conditions of the electron-phonon interaction amplification and the rise of the critical temperature of superconductive transition were defined.
