Magneto-Optical Study on Diluted Magnetic III-V Heterostructures
Abstract
This work presents polar Kerr-rotation measurements on III-V diluted magnetic semiconductors in both heterostructures (InMnAs/AlSb) and bulk films (2.5 pm InMnAs on GaAs(100)). The heterostructure shows a strong magnetooptical effect at low temperatures (5.5 K) with polar Kerr rotation θK= 0.18° at 1.65 eV and a very structured spectral dependence of θK different from that in the bulk samples. © 1993 IEEE
