Temperature dependence of thermoelegtromotive force and Nernst-Ettingshausen effect in nickel-cobalt alloys

The thermoelectromotive force and the Nernst-Ettingshausen effect for alloys of the nickel-cobalt system within the range of temperatures from room temperature to 500°C are examined in the present work. The dependence was investigated of true Nernst-Ettings-hausen constant and of thermoelectromotive force on the percentage of cobalt content in the nickel-cobalt alloys at various temperatures. The comparison of data obtained In studying the temperature dependence of the true Nernst-Ettingshausen constant Q_i and of the electrical resistivity with the theory, has indicated that Q_i is connected with electrical resistivity and temperature in the equation proposed by Kondorskii; Q_i=–( + )TTranslated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 6, pp. 43–46, June, 1972.In conclusion the authors express their gratitude to Professor E. I. Kondorskii for his interest in the study, and for discussion of the results obtained.
