双模随机晶场对混合spin-1/2和spin-1纳米管系统磁化强度的影响
Effects of bimodal random crystal field on magnetic properties of mixed spin-1/2 and spin-1 on nanotube
摘要
Abstract
The effect of atomic doping on the magnetization of nanotube lattice points was studied by u-sing the effective field theory.The results show that the doping degree,the probability of crystal field values,the nearest neighbor exchange interaction and the crystal field strength compete with each other, which make the system show rich magnetic characteristics.When the negative crystal field acts on the system,the first-order phase transition occurs.The stronger the negative crystal field,the more obvious the hindrance to the magnetization of the system.When the parameters and doping modes of crystal field are different,the evolution of the magnetization intensity on temperature exhibits unusual behaviors.关键词
