Abstract

We have measured the magnetoresistance of submicron elliptical Ni particles with Au probes. In addition to the classical anisotropic magnetoresistance (AMR), we also observe conductance fluctuations and an asymmetry with respect to magnetic field which is associated with the four terminal nature of our measurements.
