Magnetic non-linearity at strong Hall drift

Abstract

Steady current non-linear phenomena connected with a dependence of conductivity tensor components on self magnetic field of Hall drift have been investigated in aluminum. Strong Hall drift has been arranged by applying of cylinder conductor geometry, transport current being made to flow between inner and outer concentric contacts. Self magnetic field and resistivity are studied as a function of external field and transport current The role of dispersion law anisotropy and elongated electron orbits are analysed by the method of orientation averaging of conductivity tensor.
