Side-jump effect in paramagnetic amorphous metals.

Abstract

A systematic study of the resistivity (\ensuremath{\rho}), the Hall coefficients (${\mathit{R}}_{\mathit{H}}$), and the magnetic susceptibilities (\ensuremath{\chi}) of the Zr-based paramagnetic amorphous alloys suggests a self-consistent explanation for the frequently observed positive values of ${\mathit{R}}_{\mathit{H}}$ that is based on the side-jump effect. Measurements for \ensuremath{\chi}, ${\mathit{R}}_{\mathit{H}}$, and \ensuremath{\rho} of (${\mathrm{Zr}}_{0.64}$${\mathrm{Cu}}_{0.36}$${)}_{1\mathrm{\ensuremath{-}}\mathit{x}}$${\mathrm{Al}}_{\mathit{x}}$ and \ensuremath{\chi} for (${\mathrm{Zr}}_{0.50}$${\mathrm{Ni}}_{0.50}$${)}_{1\mathrm{\ensuremath{-}}\mathit{x}}$${\mathrm{Al}}_{\mathit{x}}$ alloys are presented. The odd behavior of the Hall coefficients of these alloys and the anomalous positive Hall coefficients of paramagnetic Zr-based amorphous alloys can be accounted for in terms of the enhanced spin-orbit interaction, which produces the side-jump effect.
