Abstract
The position of In3+ ions in garnet single crystals of composition {Bi 0.4Ca2.6}[Fe2-yIny] (Fe1.7V1.3)O-12 (y < 0.15) was qualitatively deter mined by the Mossbauer spectroscopy method. According to the single-io n model, the Fe3+ ions on octahedral and tetrahedral sites provided ab out the same contribution for the magnetic anisotropy of single-crysta l BiCaVIG (K-1a(V) = -0.0125 cm(-1), K-1d(V) = 0.0127 cm(-1) for y = 0 ) and BiCaInVIG (K-1a(ln) = -0.0024 cm(-1), K-1d(ln) = 0.002 cm(-1), f or y = 0.144) at room temperature.
