Thermoelectric Power and Electrical Resistance of Hydrogenated Nickel Alloyed with Transition Metals (V, Fe, Co) between 80 and 300 K

Thermoelectric power (TEP) and electrical resistance of dilute nickel alloys, Ni_TM (TM = V, Co and Fe) saturated with hydrogen at high pressure were measured between 80 and 300 K. The temperature dependence of TEP of the NiH_TM alloys obtained was found to be qualitatively different as compared to that corresponding to hydrogen-free alloys but similar to that found in Cu_TM alloys. It has been concluded that these NiH_TM hydrides are Kondo alloys.
