Description

The experimental data on high frequency resonant properties of multiferroic Nd0,75Ho0,25Fe3(BO3)4 investigated by the antiferromagnetic resonance method (AFMR) in wide frequency and temperature ranges are presented. The influence of substitution of Ho3+ ions for Nd3+ ones on resonant properties of Nd0,75Ho0,25Fe3(BO3)4 solid solution was studied. The peculiarities of field-induced spin-reorientation phase transitions for directions H || c and H || a are considered. For these directions the magnetic anisotropy changes from ''easy axies'' anisotropy to ''easy plane'' one. The AFMR modes of the Fe3+subsystem were revealed. New information about the main AFMR characteristics was obtained. It is shown that dominant in this compound is the ''easy plane'' anisotropy with a week anisotropy in the basal plane. It is for the first time that some specific features were observed in the AFMR spectra that were supposed to be due to a space-modulated spin structure (incommensurate phase) in the Nd0,75Ho0,25Fe3(BO3)4
