Abstract

The variations of the Hall coefficient R H of indium and indium rich alloys (In-Tl and In-Pb) have been measured in the range of 1∼8000 atm at room temperature. The R H or pure In increases with the rate of 3.4×10 -13 (m 3 /cou.)/katm, and changes its sign at about 8000 atm. For the sake of comparison, the variation of R H of Al and Pb have been also measured. The observed results are discussed in terms of two conceivable origins: one is the anisotropic electron-phonon scattering and the other is the effect of the lattice potential.
