摘要
采用二步最小二乘法,通过磁化曲线拟合出二元函数M(H,T)的表达式,用热力学关系式计算了Mn5Ge2.9Sb0.1的磁熵变,并与实验值进行比较,结果令人满意.
Magnetic entropy changes can be calculated accoding to the magnetization curves of Mn5Ge2.9Sb0.1,from which the function of M(H,T) was obtained by using twostep least square method.It is satisfied by contrast with the experimental results.
