Tetragonal Mn3-xGa alloys are widely recognized as hard magnets which exhibit highly anisotropic, ferromagnetic, and metallic properties. Two kinds of Mn sites, which couple antiferromagnetically. However, the difficulty in deconvolution of two kinds of Mn sites has prevented the site-resolved detailed investigations. In this study, we perform the deconvolution of each Mn site using the systematic s-ray magnetic circular dichroism (XMCD) measurements for different Mn contents in Mn3-xGa. We discuss the site-specific spin and orbital magnetic moments which are deduced from angular-dependent XMCD.
