  In order to explain the absence of hysteresis in ferromagnetic p-type
(Cd,Mn)Te quantum wells (QWs), spin dynamics was previously investigated by
Monte Carlo simulations combining the Metropolis algorithm with the
determination of hole eigenfunctions at each Monte Carlo sweep. Short-range
antiferromagnetic superexchange interactions between Mn spins - which compete
with the hole-mediated long-range ferromagnetic coupling - were found to
accelerate magnetization dynamics if the the layer containing Mn spins is wider
than the vertical range of the hole wave function. Employing this approach it
is shown here that appreciate magnitudes of remanence and coercivity can be
obtained if Mn ions are introduced to the quantum well in a delta-like fashion.
