Variational Formalism

ABSTRACTSpin-reorientation transition in magnetic thin film sandwiched by nonmagnetic materials is clarified by means of the variational formalism. Phase diagrams of the magnetization configuration are presented. Scaling relations among the film thickness, exchange coupling and magnetic anisotropies are revealed. A formula for the interface anisotropy is presented.

Two Component

Phase diagrams for diluted bulk magnetic alloys and two-component magnetic films are investigated. On the basis of the Ising model for layered structures, we calculate the transition temperature as a function of the relative concentration x by means of the variational cumulant expansion. Both the ferromagnetic and antiferromagnetic interactions are considered and the exchange coupling constants between different atoms are treated as adjustable parameters. Experimental phase diagrams in the Tc-x plane for both La 2 Cu 1-x Zn x O 4 and Sm 2 Fe 14-x Co x Si 2 are qualitatively accounted for, and phase diagrams for a randomly mixed two-component thin film of magnetic alloys are predicted.
