二维带电自旋-1/2费米气体的磁性质
Magnetic properties of two-dimensional charged spin-1/2 Fermi gases
摘要
Abstract
The magnetic properties of two-dimensional charged spin-1/2 Fermi gases confined in magnetic field and harmonic potential have been studied by introducing a spin factor which describes the competition between charge-magnetic field and spin-magnetic field interactions.It is suggested that the system presents dia-magnetism with a small spin factor, and gradually exhibits para-magnetism as the increasing of spin factor.The magnetism is separated into diamagnetic and paramagnetic regions by the critical value of spin factor which has a tiny change as the magnetic field and temperature increase.关键词
