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.

Kaufman, H. L., and F. de la Cruz. "Fluctuation induced diamagnetism in aluminum." Solid State Communications 9, no. 20 (1971): 1729–1732.
Abstract: The magnetic field and temperature dependence of the magnetization of bulk aluminum near the normal-superconductor transition has been measured. Due to the large amount of supercooling in one of the samples it was possible to extend the measurements well below the critical temperature. A comparison of the experimental results with theory is presented.
Résumé
Nous avons mesuré la dépendance en champ magnétique et en température de la magnétisation d'un échantillon massif d'aluminium au voisinage de la transition état normal-état supraconducteur. Grâce au ‘supercooling’ important d'un des échantillon, nous avons pu étendre nos mesures bien au dessous de la température critique. Nous comparons les résultats expérimentaux à la théorie.

Abstract: The low temperature specific heat of the weakly magnetic system Image U has been measured in both the normal and superconducting states. U impurities are found to enhanve the normal state electronic specific heat coefficient γ at an unusually large rate of 4.85 ± 0.50 mJ/mole °K2 at. % U. The specific heat jump at the superconducting transition for an alloy of composition 0.075 at. % U follows the BCS law of corresponding states suggesting that the system Image U is essentially non-magnetic at superconducting temperatures.

Abstract: Measurements of the specific heat jump ΔC at the superconducting critical temperature Tc on (Image )Ce and (Image )Ce Ce impurity, solid solution alloy systems indicate that the former systems obey the BCS law of corresponding states (LCS) characteristic of superconductors with non-magnetic impurities while the latter systems present deviations from the LCS linear relation between reduced parameters which are attributed to the development of localized moments at the Ce ions as the Y concentration increases.

Abstract: Perpendicular magnetic critical fields for cadmium foils were measured to thicknesses below the temperature dependent coherence length. The presence of supercooling indicates first-order thermodynamic transitions for all samples. A modification of Davies' model leads to a good fit of the experimental data.

Sereni, J. G., T. E. Huber, and C. A. Luengo. "Low temperature specific heat of Th-Gd spin glass." Solid State Communications 29, no. 9 (1979): 671–673.
Abstract: The specific heat measurements of Th---Gd alloys, with Gd concentration ranging from 0.15% to 10.8% and temperatures between 0.4 and 8 K, are reported. The characteristic spin glass specific heat enhancement and its maximum was found linearly proportional to Gd concentration. At low temperatures a T2 dependence of the specific heat was observed and the entropy associated with the magnetic ordering was the 70% of the expected value for the spin S = 7/2.

Daudin, B. "Thermal conductivity of amorphous La70Cu30." Solid State Communications 37, no. 2 (1981): 149–152.
Abstract: We have measured in a temperature range of 0.6 to 6.5 K the thermal conductivity of various samples of amorphous La70Cu30 prepared by ultra rapid quenching. Below the superconducting critical temperature (Tc=3.85K) we found the classical amorphous behaviour and determined the coupling constant n0M2. Above Tc we found that the thermal conductivity was governed by the electron-phonon interaction and we discuss the results obtained.

Huber, J. G., J. B. Bulman, and J. G. Sereni. "Superconductivity under pressure and low temperature specific heat of ThPr alloys." Solid State Communications 43, no. 12 (1982): 925–931.
Abstract: Measurements of superconducting transition temperature under pressure and low temperature specific heat are presented for ThPr alloys. At 18.2 kbar the normal- to superconducting-state phase boundary extends beyond 50 at.% Pr. This system is discussed in terms of a non-magnetic singlet ground state for the Pr3+ ions due to crystal field splitting. A splitting scheme which varies with Pr concentration is proposed.

Abstract: We measured the electrical resistivity (4–300 K), superconducting critical temperature and thermal conductivity (0.5–7 K) of the amorphous metals Zr70Cu30 and La70Cu30. Heat treatments below crystallization temperature induced changes in these properties. In particular, in the first stage of the annealing of Zr70Cu30 there are systematic changes in the thermal conductivity and the critical temperature, while the electrical resistivity remains constant. We show that there is no simple correlation between the thermal conductivity processes in the low temperature and plateau regions. We also show that the thermal conductivity of as quenched La70Cu30 is typical of amorphous metals, contrary to information previously reported.
