### Abstract:

Employing Schwinger's proper-time method, we calculate the &\langle \skew3\bar{\psi } \psi \rangle;-condensate for massive Dirac fermions of charge e interacting with a uniform magnetic field in a heat bath. We present general results for arbitrary hierarchy of the energy scales involved, namely the fermion mass m, the magnetic field strength &\sqrt{eB}; and temperature T. Moreover, we study particular regimes in detail and reproduce some of the results calculated or anticipated earlier in the literature. We also discuss possible applications of our findings.
