布洛赫电子II的轨道磁性单波段模型的应用和Landau-Peierls磁化率的修正
Orbital Magnetism of Bloch Electrons II. Application to Single-Band Models and Corrections to Landau-Peierls susceptibility
摘要：
Bloch电子的轨道极化率计算的第一次到一阶相对于相邻的原子轨道之间的重叠积分，假设单带模型。在前面的文件中开发的轨道磁化率的一般和严格的理论适用于在二维正方形和三角形晶格的单带模型。除了Landau-Peierls轨道磁化率外，还发现费米面和部分填充带中的占据态（称为带内原子抗磁性）也有相当的贡献。这说明紧束缚模型中的Peierls相在磁场的作用下是不充分的。
英文摘要：
Orbital susceptibility for Bloch electrons is calculated for the first time up to the first order with respect to overlap integrals between the neighboring atomic orbitals, assuming single-band models. A general and rigorous theory of orbital susceptibility developed in the preceding paper is applied to single-band models in two-dimensional square and triangular lattices. In addition to the Landau-Peierls orbital susceptibility, it is found that there are comparable contributions from the Fermi surface and from the occupied states in the partially filled band called intraband atomic diamagnetism. This result means that the Peierls phase used in tight-binding models is insufficient as the effect of magnetic field.
