摘　　要：在具有近邻和再次近邻交换积分下,本文就在外磁场中的体心立方结构(bcc)的任意厚度反铁磁Ising薄膜讨论了由于表面的存在对自旋结构的影响,然后精确求解了该模型的基态.<ABSTRACT>The affection, in the spin structure, due to the existence of the surfaces of ?-Ising BCC films with nearest neighbour and next nearest neighbour anti-ferromagnetic interaction in the external magnetic field is discussed, and the ground states of the films are calculated accurately.
