Abstract
It is shown within the framework of the (2+1)-dimensional P-invariant massive Gross-Neveu theory that an external magnetic field induces a first-order phase transition that breaks the P parity. The use of the obtained results in the description of magnetic phase transitions in high-T c superconductors is discussed.
