Magnetic properties of shandite-type Co3Sn2S2-xSex

We investigated the magnetic properties of polycrystalline Co3Sn2S2-xSex (0≤x ≤1.2) to ascertain the magnetism of the metallic ferromagnet Co3Sn2S2. In Co3Sn2S2-xSex, TC and magnetization gradually decrease with increasing x, but there is no magnetic phase transition from ferromagnetic throughout the full range of composition. These results indicate that Se substitution effect on magnetism is small compared with In and Ni substitution. (© 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
