Abstract: | Resistivity and thermal conductivity of the intermediate valence compound CePd3 between 1.3 and 300 K are compared with those of the nonmagnetic and magnetic reference compounds YPd3 and GdPd3 and of alloys of the type Ce1–xRExPd3 with RE=Y, Gd and 0.01<x<0.5. The analysis reveals the existence of a maximum metallic resistivity of 300 cm for CePd3. The intrinsic resistivity of CePd3 rises proportional toT2 up to 100 K, with a coefficientB about 107 times larger than e.g. in copper. We interpret this with indirect electron-electron scattering mediated through valence transitions. |
