The Magnetic Properties of B8 Type Structure Compounds in Transition Elements–Tin Systems

Abstract

The magnetic properties of all compounds with B8 type structure in transition elements-tin systems were investigated, and it was shown that Mn 1.5+ x Sn(0≤ x ≤0.3) was ferrimagnetic having the Curie temperature at about 260°K, Fe 1.3 Sn and CoNiSn were ferromagnetic having the Curie temperature at about 676°K and above 850°K, respectively, and Co 1.4 Sn Ni 1.4 Sn were paramagnetic above the liquid nitrogen temperature. The magnetic moment per mol decreases as the manganese content increases, and the magnetic moments of the compounds with the same structure in various transition metals-tin systems are explained by the assumption that the moments of iron, cobalt and nickel are successively less by one Bohr magneton than that of manganese.
