Description

The non-magnetic heavy fermion behavior of CeRuGe is destroyed by hydrogen insertion. The resulting hydride CeRuGeH, investigated by magnetization, thermoelectric, electrical resistivity and specific heat measurements, exhibits an antiferromagnetic ordering below TN = 4.0(2) K weakly influenced by the Kondo effect. Below TN, a metamagnetic double transition induced by an applied magnetic field was evidenced for CeRuGeH. This hydride presents a simple field-temperature phase diagram in comparison to that determined for the equivalent compound CeRuSiH.
