  The optic vibrational (confined and interface) modes and the electron-phonon
and hole-phonon interactions are obtained, in the dielectric continuum model,
for two diluted magnetic semiconductor structures: a single well of
Cd1-xMnxTe/Cd1-yMgyTe with the magnetic ions in the well, and a double well of
CdTe/Cd1-xMnxTe, in which a thin layer of the magnetic material is grown in the
middle of the structure. The scattering rates for the intra- and the
inter-subband transitions are obtained for electrons and holes.
