中文摘要
    利用有效场理论研究了纳米管上稀释晶场中Blume-Capel模型格点的磁化强度、内能、比热和自由能,得到了系统格点的磁化强度、内能、比热和自由能与温度和稀释晶场的关系。结果表明:稀释晶场取值概率和晶场强度等诸多因素相互竞争,使系统表现出比含恒定晶场作用的Blume-Capel模型更为丰富的磁学特性;稀释晶场会抑制系统格点的磁化强度,导致其基态饱和值小于1;温度较低时,系统格点的磁化强度表现出复杂性;晶场较强时,系统的内能、比热和自由能也呈现出不同的磁学性质。
英文摘要
    The magnetization, internal energy, specific heat and free energy of spin-1 Blume-Capel model on a cylindrical Ising nanotube with distribution of the diluted crystal field are investigated by using the effective field theory. The relationship between the magnetization, internal energy, specific heat and free energy of the system lattice and the temperature and the dilute crystal field is obtained. The results show that many factors such as the probability of the dilution of the crystal field and the intensity of the crystal field are competing with each other, making the system more rich in magnetic properties than the Blume-Capel model containing the constant crystal field. The diluted crystal field will inhibit the magnetization of the system lattice, which leads to the saturation value of the ground state less than 1. When the temperature is low, the magnetization of the system lattice is complex. When the intensity of the crystal field is strong, the internal energy, specific heat and free energy of the system also show different magnetic properties.
