1. First principles calculations of electronic structures for orthorhombic and monoclinic Cu4SnS4.

Abstract

Electronic structures of orthorhombic and monoclinic Cu4SnS4, which exhibit a first-order phase transition at 232 K, are demonstrated based on the generalized gradient approximation (GGA) of the density functional theory (DFT). The calculated band gap was 0.39 eV for orthorhombic phase, while that was not obtained for monoclinic one. These calculated results confirm monoclinic phase has smaller activation energy ( Ea) than orthorhombic phase. (© 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim) [ABSTRACT FROM AUTHOR]

2. Magnetic properties of shandite-type Co3Sn2S2- xSe x.

Author

Sakai, Yuki, Kamihara, Yoichi, and Matoba, Masanori

Subjects
POLYCRYSTALS, X-ray diffraction, SUPERCONDUCTING quantum interference devices, STOICHIOMETRY, FERROMAGNETISM, PHOTOEMISSION
Abstract

We investigated the magnetic properties of polycrystalline Co3Sn2S2- xSe x (0≤ x ≤1.2) to ascertain the magnetism of the metallic ferromagnet Co3Sn2S2. In Co3Sn2S2- xSe x, 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) [ABSTRACT FROM AUTHOR]
