Abstract

Hall currents are excited in the photorefractive sillenite crystals BSO, BGO, and BTO [Bi12Si(Ge,Ti)O20] using an externally applied magnetic field and an internal electric field of a space charge grating. We measure Hall mobilities of photoexcited electrons and obtain the values μ = (5.5±1.0) cm2V1s1 for BSO and BGO and μ = (2.5±0.5) cm2V1s1 for BTO.
