报道了对于０≤ｘ≤１的ＦｅｘＭｎ１－ｘ合金在ＧａＡｓ（００１）表面上分子束外延的结构与磁性的实验结果，当ｘ＞０８时，ＦｅｘＭｎ１－ｘ合金以单晶体心立方结构生长；当ｘ＜０３５时，则以单晶面心立方结构生长；对于０３５＜ｘ＜０８，ＦｅｘＭｎ１－ｘ生长的结构比较复杂，而正是在这一区域中，该合金发生了从铁磁相到反铁磁相的转变 The experimental results on the structure and magnetic properties of FexMn1-x alloys with 0≤x≤1 on the GaAs (001) surface were reported. When x> 08, the FexMn1-x alloy grows as a single-crystal cubic lattice structure. When x <035, it grows in a single crystal face-centered cubic structure. For 035
