Hall coefficient measurements at high perpendicular magnetic fields in polycrystalline bismuth films

Abstract

Hall coefficient measurements have been performed on polycrystalline bismuth films of 9180 A ̊ and 11 850 A ̊ thickness at different temperatures in perpendicular magnetic fields. At T=270 K , the Hall coefficient data increased in magnitude by a factor of three and saturated at high fields. Fits of the Pippard–Fawcett Hall coefficient expression were made to the data using four fitting parameters, three of which were extracted from the perpendicular magnetoresistance data at 270 K . Data at lower temperatures are presented.
