根据Kubo-Obata理论，利用Ni金属中Fletcher计算的能带、Asdente和Friedel计算的能带以及Cr金属中Lomer修正的能带，计算了Ni和Cr金属的轨道顺磁化率χ orb。在刚性带模型的假设下，计算了Ni-Cu和Cr-V合金的χ o r b In。计算值与Shimizu等人的计算值基本一致。还计算了χ o r b的温度依赖性。在镍金属和镍铜合金中，我们发现χ 0和χ 0对温度有明显的依赖性，而χ 0是不可忽略的。在Cr金属和Cr - v合金中，χ o r b几乎与温度无关。最后，估计了3 d和4 s电子的抗磁化率很小，并讨论了磁化率的场依赖性。
The orbital paramagnetic susceptibilities (χ o r b ) in Ni and Cr metals are calculated based on Kubo-Obata's theory and using the energy band calculated by Fletcher in Ni metal, the energy band calculated by Asdente and Friedel, and the one modified by Lomer in Cr metal. With the assumption of rigid band model, χ o r b In Ni–Cu and Cr–V alloys are calculated. The calculated values are in fair agreement with those obtained by Shimizu et. al . The temperature dependence of χ o r b is also calculated. In Ni metal and Ni–Cu alloys, we find appreciable temperature dependence of χ o r b and that χ s o is not negligible. In Cr metal and Cr–V alloys, χ o r b is nearly temperature independent. Finally, the diamagnetic susceptibilities due to 3 d and 4 s electrons are estimated to be small, and the field dependence of susceptibilities is discussed.
