Magnetic moment, thermal and electrical transport in the inverse Mott systems BaCo0.9Ni0.1S2−y and CuIr2S4

The antiferromagnetic BaCo0.9Ni0.1S2−y and the paramagnetic CuIr2S4 Mott systems show an inverse conductivity behavior, i.e., the metallic phase occurs at low or high temperatures, respectively, which also suggests inverse behavior in other transport properties. In this contribution we present magne...

Description
Summary:The antiferromagnetic BaCo0.9Ni0.1S2−y and the paramagnetic CuIr2S4 Mott systems show an inverse conductivity behavior, i.e., the metallic phase occurs at low or high temperatures, respectively, which also suggests inverse behavior in other transport properties. In this contribution we present magnetization data, conductivity, thermal conductivity, and Seebeck effect in the temperature range 4.2 K
