The Hall coefficient and the derivative of the density of states in amorphous metals

Abstract

The fact that there is a strong correlation between the derivative of the density of states and the Hall coefficient (R_H) in amorphous metals has been noted by a number of authors. The authors present a justification of this idea and show how this is directly related to the 'anomalous dispersion' model of Howson and Morgan (1985). They also present calculations of R_H for amorphous Cu_xZr_1-x alloys using the theory of Howson and Morgan and obtain very reasonable agreement with experiment.
