  We propose a theoretical design of a structure combining a diluted magnetic
semiconductor (DMS) layer with one-dimensional photonic crystal and show that
it allows for a sizable (a few-fold) enhancement of the magneto-optical Kerr
effect (MOKE) magnitude. We base our calculations on the transfer matrix method
assuming realistic, and optimal with respect to a sample growth, parameters. We
investigate representative cases of (Ga,Mn)N or (Cd,Mn)Te DMS layers deposited
on the top of a respectively GaN- or CdTe-based distributed Bragg reflector,
and highlight the applicability of the proposed design for both: III-V wurtzite
and II-VI zinc-blende DMS.
