Magnetostructural study of the (Mn,Fe)3(P,Si) system

Using X-ray diffraction, DSC and magnetization measurements, a magnoestructural map of the (Mn,Fe)3(Si,P) system was assembled and reported in the current paper. Besides the already known cubic phase for Mn3-xFexSi system and the tetragonal and orthorhombic phases for the Mn3-xFexP system, a novel hexagonal phase has been observed for Mn3 xFexSi1-yPy, within the approximate range of 0.2<x<2.0 and 0.2<y<0.9. Magnetization measurements both confirm and further detail the already known properties of the Mn3-xFexSi and Mn3-xFexP systems.
