| 摘 要： | 本文发展文献[1]的方法到两种不同自旋的原子(Sa=1,Sb=1/2)构成的晶格中,计算了简单立方晶格在具有再次近邻反铁磁相互作用下在外磁场中的基态自旋结构、能量和相界。从文中给出的相图可知:这种晶格有两种反铁磁自旋结构,有四种亚铁磁自旋结构。关键词：

| Abstract: | The transformation method in reference [1] is extended to treat the lattice composed of different spin atoms (Sa=l, Sb= l/2), the ground state's spin structure, energy and phase boundary of the simply cubic lattice with ihird nearest neighbors, next nearest neighbors and nearest neighbors antiferromagnetic interaction haye been calculated in an arbitrary magnetic field. We conclude that the lattice possesses two antiferromagnetic spin structures and four subferromagnetic spin structures from the phase diagrams. |
