摘要：

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 R-H is slightly temperature dependent. Using the extracted data, we calculated the electronic mean free path, coherency length xi(0) and London penetration depth lambda(L).
