Popis:	Magnetotransport data on MgB 2 thin films, fabricated on Al 2 O 3 substrates using electron–bean deposition and Mg diffusion method are reported for applied magnetic fields up to 9 T. The upper critical field anisotropy, lower critical field and irreversibility field versus temperature are determined. The Hall coefficient is slightly temperature-dependent and positive in the normal state. Using the extracted data, the electronic mean free path, coherence length ξ0, anisotropic coefficient γ and penetration depth λ are calculated.
