摘要：
We study, for the first time, magnetic properties of a system composed of two different ferromagnetic thin films with quantum Heisenberg one-half spins, coupled with each other via exchange and anisotropy interactions at finite temperatures. We use a Green function method with Tyablikov decoupling. Local magnetizations at finite temperatures are calculated self-consistently as functions of surface and interface interactions. The relevant parameters for each type of the spatial dependence of local magnetization are shown and discussed.
