Abstract We present measurements of the electrical resistivity and Hall coefficient, p and R-H, in Cr films of different thicknesses grown on MgO (100) substrates, as a function of temperature T and applied magnetic field H. The results show a low temperature minimum in rho(T), which is thickness dependent. From 40K to 2K, the Hall coefficient is a monotonous increasing function as T is reduced with no particular signature at the temperature T-min, where the minimum develops. We explain the resistivity minimum assuming an imperfect nesting of the Fermi surface leading to small electron and hole pockets. We introduce a phenomenological model which supports this simple physical picture. (C) 2013 AI Publishing LLC.
