Abstract
- Paramagnetism or diamagnetism of a material are shown by parallel or antiparallel directions, respectively, of the induced magnetization under the influence of external magnetic field. Theoretical study of paramagnetic susceptibility and diamagnetic susceptibility of non-interacting electrons system are well described by Pauli's spin susceptibility and Landau-Peierls' orbital susceptibility, respectively. For interacting electron systems, the paramagnetic susceptibility has been widely studied by using Hubbard's electron - electron interaction. However, due to its smaller value, the diamagnetic susceptibility has not been studied. To investigate the enhancement of an interacting electrons system, we study a generalized space and time-dependent orbital susceptibility of conduction electron with a repulsive Hubbard's electron - electron interaction. By using the retarded Green function expression of the space and time-dependent orbital susceptibility, we found that the orbital susceptibility is enhanced when Hubbard's electron - electron interaction is negative.<br />Comment: Presented in 6th International Conference of Asian Union of Magnetics Society 2023
