dc.description.abstractThe Hund’s coupling rule is of fundamental importance in atomic physics. It also plays a key role in determination of physical properties in strongly correlated electron systems where the Fermi energy lies in multiple bands. We report a thorough investigation of a rarely studied 4d perovskite oxide LaRuO3 by a suite of measurements including transport, magnetization, specific heat, thermoelectric powder, thermal conductivity, and neutron and X-ray diffraction. Our results are consistent with theoretical predictions, which make LaRuO3 an exemplary Hund metal.
