Free-Standing GaMnAs Nanomachined Sheets for van der Pauw Magnetotransport Measurements

Free-Standing GaMnAs Nanomachined Sheets for van der Pauw Magnetotransport Measurements

We report on the realization of free-standing GaMnAs epilayer sheets using nanomachining techniques. By optimizing the growth conditions of the sacrificial Al0.75Ga0.25As layer, free-standing metallic GaMnAs (with ~6% Mn) microsheets (with TC ~85 K) with integrated electrical probes are realized for...
