14 Dec 2004 | | Subject: | Strongly Correlated Electrons; Other | cond-mat.str-el cond-mat.other | | Affiliation: | Department of Phhysics and Astronomy, University of Missouri, Columbia, Department of Physics and Astronomy, Iowa State University/Ames Laboratory, Center for Neutron Scattering, Oak Ridge National Laboratory, Chemistry Department, Purdue University | | Abstract: | We present magnetoresistance and Hall-effect measurements on single crystal magnetite Fe3O4 close to the Verwey transition Tv = 123.8 K. We show that the formation of grain boundaries accompanying the reduction in crystal symmetry plays a significant role in the electron scattering mechanism, and that grain boundaries can account for the apparent change in sign of the charge carriers below Tv. | | Source: | arXiv, cond-mat/0412375 | | Services: | Forum | Review | PDF | Favorites | |
