Structure and magnetism in metastable bcc Co1−xMnx epitaxial films

Co-rich Co1−xMnx alloys have hcp or fcc disordered phase and those ferromagnetic orderings are significantly deteriorated with increasing Mn concentration x in bulk. On the other hand, those metastable bcc phases show properties attractive to magnetics and spintronics, as studied recently. Here, we report systematic study of structure and magnetism for epitaxial thin films. The single phase bcc Co1−xMnx(001) films were pseudomorphically grown on Cr(001) for 0.14更多
