The Bose-Einstein condensation temperature Tc for a system of coupled quantum dots in a microcavity was estimated in function of the confining potential steepness, the external magnetic field strength, and the barrier layer width for indirect excitons. The effect of the magnetic field on Tc was found to be nonmonotonic over a certain range of the control parameters. The reason is the presence of two competing mechanisms accompanying the increase of the magnetic field: (a) increase of the magnetoexciton effective mass and (b) increase of the effective confining potential steepness for quantum dots.
