Strong enhancement of magnetic ordering temperature and structural/valence transitions in EuPdS under high pressure.

We present a comprehensive study of the inhomogeneous mixed-valence compound, EuPdS, by electrical transport, X-ray diffraction, time-domain Eu synchrotron Mössbauer spectroscopy, and X-ray absorption spectroscopy measurements under high pressure. Electrical transport measurements show that the antiferromagnetic ordering temperature, , increases rapidly from 2.8 K at ambient pressure to 23.

A Low-Temperature Structural Transition in Canfieldite, AgSnS, Single Crystals.

Canfieldite, AgSnS, is a semiconducting mineral notable for its high ionic conductivity, photosensitivity, and low thermal conductivity. We report the solution growth of large single crystals of AgSnS of mass up to 1 g from a ternary Ag-Sn-S melt. On cooling from high temperature, AgSnS undergoes a known cubic (4̅3) to orthorhombic (2) phase transition at ≈460 K.
