- Magnetotransport properties of pure Mg metal and MgB₂ samples with varying amounts of unreacted Mg are systematically studied in magnetic fields up to 18 T. With increasing quantity of Mg, the inhomogeneous MgB₂ samples show greatly decreased residual resistivity, enhanced residual resistance ratio (RRR) and enhanced magnetoresistance (MR), gradually approaching the transport behaviors of pure Mg metal. We use the generalized effective medium theory to show that the large RRR and MR of the inhomogeneous MgB₂ samples can be quantitatively explained by a two-phase model in which the two phases are MgB₂ and pure Mg.
