摘要：

Single crystal Co2MnGe Heusler alloy films were epitaxially grown on GaAs substrates by molecular beam epitaxy. The films have the bulk L2(1) crystal structure as determined by reflection high energy electron diffraction patterns and x-ray diffraction. A high saturation moment of 1006 emu/cm(3) at room temperature has been measured. Ferromagnetic resonance of these ordered alloy films shows narrow linewidths and a small anisotropy. A room temperature resistivity of 115 mu Omega cm and a 0.11% anisotropic magnetoresistance has also been determined. (C) 2000 American Institute of Physics. [S0021-8979(00)65208-8].
