Manifestation of dissimilar types of magnetism in iron- and chromium-substituted MnSnS.

MnSnS belongs to the MII2AQ (M = transition metal; A = Si, Ge and Sn; Q = S, Se and Te) class of compounds that crystallizes in the orthorhombic space group and shows complex magnetic properties. Here we report the synthesis and magnetic properties of Fe- and Cr-substituted MnSnS quaternary chalcogenides. All these compounds have been synthesized using a high-temperature solid-state route.

Nominal Effect of Mg Intercalation on the Superconducting Properties of 2H-NbSe.

2H-NbSe is a phonon-mediated, Fermi-surface topology-dependent multiband superconductor with an incommensurate charge-density wave (CDW) that coexists at a local level with superconductivity. Usually, the intercalation in 2H-NbSe enriches the CDW, enhances the -axis lattice parameter, and distorts the Fermi surface, which result in a decrease in the superconducting transition temperature (). The rate of decrease of depends on the electronic structure, size, valence, magnetic nature, and electronegativity of the intercalating species.

Mixed-valent antimony-induced disorder in substituted antiferromagnetic MnSnS.

Among MII2AIVQ4 (M = transition metal; A = Si, Ge, and Sn; Q = S, Se, and Te)-type compounds, most of which crystallize in an olivine or spinel structure, Mn2SnS4 is a unique compound that crystallizes in the orthorhombic space group Cmmm and exhibits complex magnetic properties. In this article, we report synthesis and study of the effect of Sb substitution (up to 20%) on the magnetic properties of Mn2SnS4. All the compounds were found to be in a single phase and indexed with the orthorhombic parent structure.
