Hall resistance vs magnetic field
WebApr 8, 2024 · Figure 1. Magnetoresistance trace measured on a Corbino disk on the (001) surface using a pulsed magnetic field up to 80 T at 1.4 K. The negative magnetoresistance above 80 T, indicated with the arrow, is due to a surface-to-bulk crossover behavior, where the bulk channel starts to dominate the transport, consistent with the reduction of … WebMagnetoresistance is the change in resistance corresponding to an applied electric field because of the effects of a simultaneously applied magnetic field. In the Hall-effect geometry, to be specific, it means a change in electrical resistance corresponding to an electric field E x because of B z .
