PREPARATION OF IRON PHOSPHIDES, IRON BORIDES, COBALT BORIDES AND TERNARY ALLOYS OF BORON OR PHOSPHORUS WITH FE, CO, NI, MN AND THE STUDY OF THEIR DIFFERENT MAGNETIC PROPERTIES

Abstract

The study of iron phosphides was completed. Co2P and some ternary phosphides of Fe-Co-P were prepared. The ternary alloys, (Me1, Me2)2B type and (Me1, Me2)B type, Me1 and Me2 being transition metals were studied. The FeP phosphide was ferromagnetic with a Curie point at 215 K. FeP2 was paramagnetic with negative Curie points. (Fe, Co)2B and (Fe, Ni)2B alloys and some among the (Co, Ni)2B and (Fe, Mn)2B alloys were studied. Curie points and magnetic moments were determined. Curie points of Fe2(1-x) Ni2xB decreased rapidly with increasing Ni content. Ferromagnetism of Co2(1-x) Ni 2xB and Fe2(1-x)Mn2xB disappears for values of x, above 50%. (Author)
