抄録
Nano-size MnSb clusters with a nominal thickness of 3 ML were grown on GaAs(111)B substrates by molecular beam epitaxy. The films were capped with GaAs, and the magnetoresistance effect was investigated at room temperature. A large positive magnetoresistance effect of over 50% was observed. The dependency on the sweep rate of magnetic field and an effect of Cr-doping in GaAs capping layers were investigated. The photoinduced MR effect was also observed under laser-irradiation with a photon energy above the band gap of GaAs. It is shown that these phenomena can be attributed to the enhancement of the conductivity by photogenerated carriers.
