  • 摘要

    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xxMn1-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.

     

    Abstract

    The experimental results about structures and properties of FexMn1-x alloys grown epitaxially on GaAs(001) surface have been reported.For x>0.8, the FexMn1-x alloy grows in single crystal line bcc structure,and for xxMn1-x alloy film transforms from ferromagnetic phase to antiferromagnetic one.
