Title On the evidence for electron-electron scattering in the electrical resistivity of In Type Journal Article
Year 1970 Publication Solid State Communications Abbreviated Journal Solid State Commun.
Volume (down) 8 Issue 24 Pages 2129-2133
Keywords
Abstract Experimental measurements of the electrical magnetoresistivity of high purity Indium at low temperatures have been performed and clearly indicate that:

1. (a) A generalized Kohler's rule can be used to describe all experiments.

2. (b) A reliable method is therefore obtained for extrapolating the zero magnetic field resistivity to temperatures below the superconducting transition temperature.

3. (c) Clear-cut and reliable data show that no T2 dependence of the resistance is found; therefore no evidence of electron-electron interaction appears, contrary to information previously reported in the literature.

Title T^5 law and Matthiessen's rule Type Journal Article
Year 1975 Publication Journal of Physics F: Metal Physics Abbreviated Journal J. Phys. F: Met. Phys.
Volume (down) 5 Issue 3 Pages 481
Keywords
Abstract Precise electrical resistivity measurements on very dilute non magnetic indium alloys show no doubt in a T 5 dependence on temperature between 1-4K and strong deviations from Matthiessen rule. Measurements of thermal resistivity show that the extrapolation method to obtain the data to H=0 is correct. Comparison of the results with recent theories is discussed.

Title Low angle electron scattering in thermal resistivity Type Journal Article
Year 1975 Publication Journal of Physics F: Metal Physics Abbreviated Journal J. Phys. F: Met. Phys.
Volume (down) 5 Issue Pages 1902-1909
Keywords
Abstract Electrical ( rho ) and thermal (W) resistivity measurements in very dilute In alloys between 1K and 4K show a temperature dependence expressed by rho = rho 0+ beta T5 and WT=(WT)0+AT3+BT5. The BT5 term in the thermal resistivity is due to a contribution from a 'diffusion-like process' of electrons over the Fermi surface, as is the one that describes the temperature dependence of the electrical resistivity. This claim is supported by the experimental fact that the Lorenz number defined as L= beta /B coincides with the value given by L= rho 0/(WT)0 which in turn agrees with the free electron value within 15%.
