Popis:	Magneto-transport and magnetic data on MgB 2 polycrystalline samples are reported for applied magnetic fields up to 9 T. In the normal state we find that MgB 2 compound has a temperature and field-dependent resistivity behavior like a simple metal. The critical magnetic field Hc2(T) and the irreversibility field Hirr(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 λL.
