Magneto-Optical Effects Enhancement in DMS Layers Utilizing 1-D Photonic
Crystal    [PDF]

M. Koba, J. Suffczyński

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.
