Structural and magnetic changes with composition in the (Fe1-xMnx)2P system with 0.01<or=x<or=0.85 have been investigated by means of X-ray diffraction and 57Fe Mossbauer spectroscopic techniques. (Fe1-xMnx)2P crystallises with the hexagonal Fe2P-type structure for x<0.24 and x>0.70 and with the orthorhombic Co2P-type structure for 0.26<x<0.68. Manganese substitutes preferentially for iron at the Fe(2) position in both the Fe2P and Co2P structures. Magnetic hyperfine fields, centroid shifts and quadrupole splittings are reported, as well as the results of magnetisation measurements for (Fe0.97Mn0.03)2P at 4.2K in fields up to 12 T.
