Abstract

Measurements of the low field Hall coefficient R H 0 and the transverse magnetoresistance δϱ/ ϱ 0 of aluminum alloys with 1.872 and 2.30 at.% Cu have been made in a magnetic field up to about 40 kG and 4.2 K. The samples were quenched from 540°C into iced water and aged at room temperature in order to form Guinier-Preston zones. The results show that the low field Hall coefficient R H 0 depends very markedly on the potential of copper impurities and not on the chemical composition of the alloys.
