Coexistence of magnetism and superconductivity in thin films of the Fe-based superconductor BaLaFeAs.

Magnetization measurements have been performed to understand the role of the magnetic structure on the superconducting properties of epitaxial thin films of BaLaFeAs(= 0.08, 0.13, and 0.

Fracture structure and thermoelectric enhancement of CuSe with substitution of nanostructured AgSe.

Recently, copper chalcogenides have attracted great attention due to their potential application for mid- to high-temperature thermoelectric power generation. In this work, we report the thermoelectric properties of Cu2Se compounds with different sample preparation processes and the inclusion of a nanoscale Ag2Se powder synthesized with a unique wet chemistry procedure. The Cu2Se compounds were prepared by solid state reaction (SSR), fast quenching (FQ) and mechanically alloyed with nanostructured Ag2Se (NM) followed by hot pressing.
