Abstract

Conversion electron Mössbauer effect measurements have been performed on the (111)-oriented (Bi, Y)3Fe5O12 single-crystal films at room temperature. The dependence of the isomer shift (δ) and magnetic hyperfine field (Hhf) of the 24d site on Bi concentration shows that the degree of covalence of the bond decreases with Bi concentration and the change of Hhf is not directly proportional to that of the 24 d sublattice magnetization. The values of δ and Hhf of the 16a site are kept at almost the same value. The magnetic structure of the (Bi, Y)3Fe5O12 films is collinear ferrimagnetic and the direction of the net magnetization of the Bi3Fe5O12 film is along the <110> axis.
