低温下镍的磁化强度与温度的关系

On the Relationship Between Magnetization of Nickel and Temperature at Low Temperature

依据实验测定的低温下镍的磁化强度与温度的关系曲线,采用自旋波的量子化理论可推得低温下磁振子的磁化强度的变化分数ΔM/M(0)与T3/2成正比。此结论与低温下镍的磁化强度与温度关系的实验曲线十分接近。

According to the curve of the relationship between the magnetization of metal nickel and temperature measured by experiment, applying quantization theory of spin wave, the magnetization variation ratio ΔM /M （0） of the magnon with a T3/2 dependence at low temperature was derived, which is in accordance with experimental results.
