Abstract

A magnetic characterization of a single crystalline bismuth iron garnet film was done by applying conversion electron Mössbauer spectroscopy (CEMS). To examine the temperature dependence of sublattice magnetization, CEMS measurements were made at 6, 78, 290 and 670 K, i.e. in both the ferrimagnetic and paramgnetic regions. The magnetic and quadrupole hyperfine interactions as compared with those in other garnets like YIG indicated continuous effects of lattice expansion. The temperature dependence of the sublattice magnetization has been explained at the present stage by the two-sublattice molecular field model using parameters slightly modified from those of YIG.
