Conversion electron Mossbauer studies on strontium ferrite films with in-plane and perpendicular anisotropies

Abstract

Hexagonal strontium ferrite thin films with in-plane and perpendicular magnetic anisotropies have been studied using conversion electron Mossbauer spectroscopy. The hyperfine parameters of the films were found to be similar to the one obtained for bulk strontium ferrite. However, the intensity ratios of the first and second lines of the Mossbauer spectra were found to be different for films deposited at different rf powers. This indicated a change in the anisotropy of the deposited film. The resultant change in the magnetization direction and crystallization texture was compared to other measurements, (C) 1998 American Institute of Physics. [S0021-8979(98)20111-3].
