Abstract

Magneto-transport and magnetic data on MgB₂ polycrystalline samples are reported for applied magnetic fields up to 9 T. In the normal state we find that MgB₂ compound has a temperature and field-dependent resistivity behavior like a simple metal. The critical magnetic field H _c2 (T) and the irreversibility field H_irr(T) curves were determined. The Hall coefficient RH is slightly temperature dependent. Using the extracted data, we calculated the electronic mean free path, coherency length ξ₀ and London penetration depth λ_L.
