摘要
对郎之万函数进行数值计算,拟合出超强磁场中顺磁性物质的磁化率计算公式。结果发现,不同于弱磁场中的磁化率只与温度有关,超强磁场中的磁化率与温度和磁场强度都有关。
It calculated the Langevin function numerically and fited out a formula for the magnetic susceptibility of paramagnetism in ultra-strong magnetic field.It is found that the magnetic susceptibility in strong field has a relationship both with the temperature and the field strength.This is different with the magnetic susceptibility in weak field where it is determined only by temperature.
