摘要
用有效地的理论，我们学习了 aspin-1/2 Ising 超点阵的磁性，它由三不同铁磁物质材料组成。这超点阵的磁性的行为被检验。批评温度和赔偿 tempratureof 系统越过接口并且在 intraface 作为在 nearest-neiboringspins 之间的交换相互作用的一个函数被学习。magenetizations 的温度依赖也被给。
Using the effective-field theory we studied the magnetic properties of a spin-1/2 Ising supedattice, which consist of three different ferromagnet materials. The magnetic behavior of this superlattice is examined. The critical temperature and the compensation temprature of the system are studied as a function of the exchange interactions between the nearest-neiboring spins across the interface and in the intraface. Temperature dependence of magenetizations is also given.
