Nouvelle méthode de mesure rapide du pouvoir thermoélectrique aux très basses températures de petits échantillons. Application au cobalt monocristallin
Year: 1971
Type: article
Abstract: A new technique is described for rapid measurement of the thermoelectric power of single crystal samples or brittle materials over a wide temperature range. The technique eliminates spurious thermal emf's in the leads and is based upon recording of the thermoelectric emf of the sample/lead-wire and the sample/Gold at 0,03 % iron couples. The temperature gradient along the specimen is deduced. The main advantage of the method is that all the wires are in good thermal and electrical contact with the sample. As a test of this technique, the thermopower of a single crystal of cobalt was measured between 7 and 80 °K. A comparison with magnesium is given.
