Abstract

The magnetic and structural properties of ferrimagnetic (FRI) Mn1.9Fe0.1Sb0.9Sn0.1 with a Cu2Sb-type tetragonal structure were studied by magnetization and high field X-ray diffraction (XRD) measurements in 10 ≤ T ≤ 773 K and in magnetic fields μ0H up to 5 T. The lattice parameters a and c at 285 K were estimated to be 0.407 nm and 0.655 nm, respectively. The saturation magnetization at 10 K was determined to be 39.1 Am2/kg. It was observed that a first order magnetic transition (FOMT) with a thermal hysteresis occurred in the vicinity of 310 K under low magnetic fields. This FOMT disappeared easily by applying magnetic fields over 0.4 T.
