LOW-FIELD HALL-COEFFICIENT OF AL-4D DILUTE ALLOYS - THE ROLE OF THE ANISOTROPIC IMPURITY SCATTERING

The role of the anisotropic impurity scattering in the determination o f the low-field Hall coefficient of Al-4d dilute alloys is investigate d by means of systematic theoretical calculations, as well as experime ntal measurements for Al-Zr and AI-Mo. The theoretical results, obtain ed without using any adjustable parameter, are in excellent agreement with the experimental data and a consistent interpretation of the syst ematic variation of the low-field Hall coefficient for aluminium-based dilute alloys with transition-metal impurities is given.
