X-ray diffraction and transmission electron microscopy have been used to study the microstructure of copper foil during rolling. Annealing was used to release work hardening of rolled copper foil (RCF), and electrical conductivity was determined by use of a PPMS-9 comprehensive physical property-measurement system. The microstructure and electrical conductivity of RCF are discussed. Our results showed that the relative intensity of the (220) diffraction peak increased continuously with decreasing sample thickness and that rolling induced preferred orientation. Many obvious crystallographic defects were present; these seriously affected electrical conductivity. The electrical conductivity of RCF decreases with increasing lattice distortion and micro defects which occur during deformation, especially when the surface adsorbs lubricant. However, annealing reduced lattice distortion and the scattering of conducting electrons at these defects, thus improving the electrical properties. For foil thickness in the range 25-180 lm, annealing temperatures in the range 150-300°C, and annealing times in the range 2.5-3.0 h, the electrical conductivity of RCF increased with increasing thickness and annealing temperature, and decreased with increasing annealing time.

Centre de Recherches sur les Très Basses Températures, C. N. R. S., Cedex 166 38, Grenoble-Gare (Reçu le 1 er avril 1971) Résumé. 2014 Nous décrivons deux montages qui permettent de déterminer le facteur de surtension d'échantillons conducteurs en résonance électromagnétique à basse température, l'un à 100 MHz, l'autre à 2,4 GHz. Un même circuit équivalent, à composants discrets, sert à analyser les résultats obtenus avec les deux montages. Nous montrons l'application de ces montages à l'étude d'une ligne coaxiale supraconductrice de 1,42 m de long, d'une part, et à la détermination des propriétés de supraconducteurs de type II dans un champ magnétique, d'autre part. L'examen des résonances nous permet d'affirmer la validité du circuit et le bon fonctionnement des appareils.Abstract. 2014 We describe two experimental setups with which we can determine the Q-factor of conducting specimens in electromagnetic resonance at low temperature, one at 100 MHz, the other at 2.4 GHz. The same equivalent circuit of lumped components is adopted for the analysis of the results from each setup. We show the applications to the study of a 1.42 m long superconducting coaxial line and to the determination of the properties of type II superconductors in a magnetic field.By examining the resonances we can affirm that the equivalent circuit is valid and that the two circuits function correctly.
