| Abstract: | Based on the Mossbauer spectra of indium Substituted garnet single crystals of composition{Bi0.4Ca2.6 } Fe2-yIny] (Fe1.7V1. 3 ) O12 it is shown that nonmagnetic ion In3- substituted forFe3 on the octahedral sites. Magnetocrystalline anisotropy was studied according to the single ion model. It was concluded that the Fe3 ions on octahedral and tetrahedral sites provided the same contribution for the magnetic anisotropy of the garnet single crystals BiCaVIG(K1a=-0. 012cm-1, K1d=0. 0127cm-1 for y=0) and BiCaInVIG (K1a=-0. 0024cm -l,K1d= 0. 002cm-1 for y= 0. 144 ) at room temperature. |
