Abstract

Magnetotransport properties of pure Mg metal and MgB 2 samples with varying amounts of excess Mg were systematically studied in magnetic fields up to 18 T. It is found that the both the Mg and inhomogeneous MgB 2 samples show large low temperature conductivity, residual resistance ratio (RRR) and magnetoresistance (MR) under high fields. Calculations of the generalized effective medium theory show that the large RRR and MR of the inhomogeneous MgB 2 samples can be explained by unusual magnetotransport properties of pure Mg metal.
