Ni substitution effect on magnetic and transport properties in metallic ferromagnet Co3Sn2S2

Abstract: We investigated the magnetic and transport properties of polycrystalline to ascertain the magnetism of the new metallic ferromagnet . In magnetization does not saturate up to 5.5T at 10K, and the estimated saturation moment () is small ( per Co atom). In (, the electrical resistivity shows metallic behavior without a hump but has a kink at . The and magnetic susceptibility gradually decrease with increasing x, and there is no antiferromagnetic phase throughout the full range of composition. These results indicate that is a weak itinerant ferromagnet; while, the same order of the Rhodes–Wohlfarth value as suggests the existence of a localized moment. [Copyright &y& Elsevier]
