摘要：

Polycrystalline　Mn1.1Fe0.9P0.76Ge0.24　was　prepared　by　mechanical　alloying　and　spark　plasma　sintering.　Neutron　diffraction　was　used　to　determine　the　structure　of　the　title　compound,　and　its　nuclear　and　magnetic　structures　were　refined　using　the　Rietveld　method.　It　is　found　that　temperature　and　magnetic　field　can　induce　phase　transition　between　the　paramagnetic　and　the　ferromagnetic　phases　in　the　material,　and　the　paramagnetic　and　ferromagnetic　phases　have　very　distinct　crystal　structures　and　different　Ge　contents.　(C)　2010　International　Centre　for　Diffraction　Data.　[DOT:　10.1154/1.3478986]
