In this article, we have reported the magnetic and electrical transport properties of the disordered Mn2Sb material. XRD, XPS, and ED AX measurements have been carried out to study the elemental compositions and the structural disorder. DC magnetization and AC magnetic susceptibility data establish long-range magnetic ordering in this disordered material. In zero field cooled (ZFC) conditions, when magnetization is measured at a very low magnetic field, we find negative magnetization in a specific temperature range in this material. An upturn in resistivity, i.e., a negative temperature coefficient of the resistivity behavior, is happening in the region with the lowest temperatures. The Curie temperature of this disordered Mn_2Sb material has not changed significantly, and it is 8 K larger compared to the previous reported value for the pure ordered structure. T = 0 K DFT calculations were done to explain the low-temperature magnetic behavior of this material.
