An out-of-plane magnetic field is applied and swept to extract the Hall resistance in the samples. WebApr 1, 2008 · Low field measurements as a function of temperature (T c =24 K) of the a sample showing weakly localized behavior exhibit two changes in the sign of the Hall resistance vs. magnetic field (H) at 150 mT ().Since the AH coefficient is proportional to the Hall resistance at low fields, this implies a sign change in the AH coefficient. aki prerenal intrarenal
