Finite Size Effects in Field-Induced Transitions in Magnetic Multilayers

摘要

The technique of finite difference equations is used for an analytical investigation offield-induced transitions in magnetic multilayers. Heisenberg and biquadratic exchange interactionsand uniaxial anisotropy are taken into account. The analytical dependencies of critical field valuesdetermining the stability of ferromagnetic and antiferromagnetic phases on the layers number areobtained.
