  The Dirac oscillator in a homogenous magnetic field exhibits a chirality
phase transition at a particular (critical) value of the magnetic field.
Recently, this system has also been shown to be exactly solvable in the context
of noncommutative quantum mechanics featuring the interesting phenomenon of
re-entrant phase transitions. In this work we provide a detailed study of the
thermodynamics of such quantum phase transitions (both in the standard and in
the noncommutative case) within the Maxwell-Boltzmann statistics pointing out
that the magnetization has discontinuities at critical values of the magnetic
field even at finite temperatures.
