Magnetic non-linearity at strong Hall drift

Abstract

Steady current non-linear phenomena connected with the dependence of conductivity tensor components on self magnetic field ofHall drift have been investigated in aluminum polycrystalline conductors. 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 an external field, transport current densities and temperature. The self magnetic field magnitude in this geometry achieves the levels of external field. The role of dispersion law anisotropy and elongated electron orbits are analysed by the method of orientation and kinetic averaging of conductivity tensor during charge diffusion.
