Abstract
The magnetization, geff and linewidth ΔH∥ and ΔH⊥ for liquid‐phase‐epitaxially grown thin films of EuxY3−xFe5−yGayO12 (0.2≤x≤1.2; y=1.0) have been investigated in the temperature range 85–420 K. ΔH versus temperature curves show maxima which occur at about the same temperature as that observed in bulk single crystals of EuIG, but the width of the curves is narrower in the LPE films. The temperature and composition dependence of geff and ΔH have been explained on the basis of the three sublattice model and a new relaxation mechanism based on anisotropic exchange.This publication has 12 references indexed in Scilit:
