利用高灵敏度超导量子干涉仪和磁力显微镜，我们推断出MnAs/GaAs（001）薄膜存在一个小的面外磁化分量。它的温度依赖性与主导的面内磁化强度有很大不同，特别是在MnAs薄膜的相变温度以上仍然可以检测到。我们的测量结果表明，平面外的组件是由于小的孤立的磁性“晶粒”内的膜。(C)2003年，美国物理学会。
From highly sensitive superconducting quantum interference device magnetometry and magnetic force microscopy, we deduce a small out-of-plane magnetization component of MnAs/GaAs(001) films. Its temperature dependence is substantially different from the dominating in-plane magnetization, particularly as it is still detectable above the phase transition temperature of MnAs films. Our measurements indicate that the out-of-plane component is due to small isolated magnetic "grains" within the film. (C) 2003 American Institute of Physics.
