Pauli and orbital effects of magnetic field on charge density waves

Taking into account both Pauli and orbital effects of external magnetic fie ld we compute the mean field phase diagram for charge density waves in quas i-one-dimensional electronic systems. The magnetic field can cause transiti ons to CDW states with two types of the shifts of wave vector from its zero -held value. It can also stabilize the field-induced charge density wave. F urthermore, the critical temperature shows peaks at a new kind of magic ang les.
