Abstract
The magnetic properties of single crystals of erbium iron garnet (ErIG) were studied in applied fields up to 150kOe between 1.4 and 300K. At low temperature, the macroscopic easy direction of the bulk magnetization is [100]; below the compensation temperature (80±2K), the magnetization presents non-linear field evolution. On the assumption of an isolated ground doublet, the anisotropy constantsK i (i=1,2) of ErIG are given byK i (Er)+K i (YIG); theK i are calculated as a function of theG andg tensor components. It is worthwhile noting that theK i (Er) are strongly temperature dependent; so at low temperature the anisotropy of the garnet is determined by the rare earth ions, while in the 50 K regionK1(Er) becomes comparable toK1(YIG) with the opposite sign which results in a very weak anisotropy of the garnet. Above 50 K,K1(YIG) is predominant and the Fe3+ ions determine the garnet anisotropy.
