摘要：

We consider Dirac fermions moving in a plane with a static homogeneous magnetic field orthogonal to the plane. We calculate the effective action at finite temperature and density. The magnetization is derived and it is shown that the fermion gas exhibits de Haas-van Alphen oscillations at small temperatures and weak magnetic fields. We also comment upon earlier work. © 1995 The American Physical Society.
