The magnetic properties (phase diagrams and magnetizations) of two mixed-spin Ising bilayer films with a transverse field are investigated by the use of the effective field theory with correlations. The systems consist of two magnetic atoms where spin-1/2 atoms are directed to the -direction and only spin-1 atoms are canted from the -direction by applying a transverse field. We examined how magnetization sign reversal can be realized in the system, due to the effects of the transverse field on the spin-1 atoms. The compensation point phenomena are found in both systems, depending on the selections of physical parameters. However, the reentrant phenomena are found only for one of the two systems.
利用含关联的有效场理论研究了两个具有横向场的混合自旋伊辛双层膜的磁性（相图和磁化强度）。系统由两种磁性原子组成，其中自旋为1/2的原子沿 - 方向排列，而仅自旋为1的原子通过施加横向场而偏离 - 方向。我们研究了由于横向场对自旋为1的原子的影响，系统中如何实现磁化强度符号反转。根据物理参数的选择，在两个系统中均发现了补偿点现象。然而，重入现象仅在两个系统中的一个中被发现。
