摘要：

The occurrence of a maximum in the measured Hall coefficient RH of noble metals at low temperatures is discussed in terms of a phonon drag mechanism proposed by Alderson, Farrell and Hurd (1968) and the Ettingshausen-Nernst effect. Results of Hall effect measurements are presented for α phase Cu-Zn alloys between 4·2 and 300°k in which a search for phonon drag effects was made. It is concluded that phonon drag effects are too small to play a significant role in determining the Hall coefficient and an alternative explanation for the maximum in RH, involving suppression of Umklapp processes from the neck regions of the Fermi surface, is given. © 1969 Taylor & Francis Group, LLC.
