摘要：
We present magnetotransport properties, with emphasis on Hall effect, of a new class of III-V based magnetic (GaMnAs)/nonmagnetic (AlAs) semiconductor superlattices (SLs) grown by low-temperature molecular beam epitaxy. The SLs having relatively wide (GaMn)As layers (greater than or equal to 70 Angstrom) are ferromagnetic at low temperatures, and their hole concentrations and Curie temperatures are estimated through the analysis of Hall measurements. The dependence of the magnetic and transport propel-ties on the GaMnAs well width is discussed. (C) 1998 American Institute of Physics.
