H. Shimizu et al., Enhanced magneto-optical effect in a GaAs : MnAs nanoscale hybrid structure combined with GaAs/AlAs distributed Bragg reflectors, J VAC SCI B, 18(4), 2000, pp. 2063-2065
We present significant enhancement of magneto-optical effect at room temper
ature in GaAs with MnAs magnetic nanoclusters sandwiched by GaAs/AlAs multi
layers acting as distributed Bragg reflectors. The experimentally observed
transmissivity and magneto-optical spectra are well explained by theoretica
l calculations. This new material system will open up the possibility of re
alizing nonreciprocal magneto-optical devices integrated with semiconductor
optoelectronic devices and circuits. (C) 2000 American Vacuum Society. [S0
