Abstract

Photoinduced Hall currents are generated in a photorefractive strontium barium niobate crystal by excitation of non-steady-state holographic currents and by application of a modulated external magnetic field. Electrons are the dominant photoinduced charge carriers, and the Hall mobilities μ for migration along and perpendicular to the $\mathbf{c}$ axis are determined as ${\mu }_{\parallel c}=(4\pm 1)\times {10}^{-6} {\mathrm{m}}^2 {\mathrm{V}}^{-1} {\mathrm{s}}^{-1}$ and ${\mu }_{\perp c}=(1.3\pm 0.3)\times {10}^{-6} {\mathrm{m}}^2 {\mathrm{V}}^{-1}{\mathrm{s}}^{-1}.$
