Thickness-dependent magnetic properties of inverse spinel Fe₃O₄

ABSTRACT

Effect of film thickness on the magnetic properties of inverse spinel $\left({\mathrm{F}\mathrm{e}}_{}^{3+}\right)\left[\mathrm{F}{\mathrm{e}}^{3+}\mathrm{F}{\mathrm{e}}^{2+}\right]{\mathrm{O}}_4^{2-}$ has been studied using Monte Carlo simulation. The critical temperature has been obtained for different film thickness up to L = 13. The free boundary conditions along L direction have been used. The magnetic hysteresis is obtained for different temperatures and for different film thickness up to L = 7. The magnetic coercive field and remanent magnetization increase with increasing the thickness of the film and decrease with increasing the temperature values.
