Abstract

We report the fabrication and magnetotransport properties of nanoscaled clusters of manganese antimonide (MnSb) grown on sulfur-passivated GaA(001) substrates by molecular-beam-epitaxy (MBE). The typical diameter and height of dots were about 22 nm and 4 nm, respectively. Uniform dots in size were formed in a self-assembled mode. Magnetotransport properties of MnSb granular films were investigated, and the anisotropic magnetoresistance were observed at room temperature. Large jumps appeared at 9 K in magnetoresistance curves, and the jump structure depends on the sweep rate of the magnetic field. These magnetotransport properties describe well the magnetic behavior of MnSb dots.
