CONDUCTIVITY AND HALL CONSTANTS. XXIII. THE TEMPERATURE DEPENDENCE OF THE RESISTANCE AND THE HALL CONSTANT OF PALLADIUM MIXED CRYSTALS (in German)
The temperature coefficient of resistivity and Hall constant at room temperature were measured on alloys of Pd with Ag, Cd, In, Rh, Ru, Mo, Nb, Zr, and V. Starting from pure Pd, the absolute temperature coefficient of resistivity DELTA /sub q// DELTA T is decreased by all alloying additions. This fact is mainly due to the filling up of the d-band by the electrons of the solute. The amount of the absolute temperature coefficient of the Hall constant DELTA R/ DELTA T also decreases in every case. This change is far more pronounced than that of the temperature coefficient of resistivity and leads to a change of sign for many alloys at additions of only 2 at.% alloying element to Pd. This effect is also connected with the d-band of Pd. Comparing it with the behavior of the thermoelectric power of these alloys, however, suggests that this pronounced change is mninly caused by the scattering of the electrons at solute atoms. (auth)
