We have used a three term polynomial expression to approximate electrical and magneto transport properties of epitaxial La0.67Sr 0.33MnO3 (LSMO) thin films in wide temperature range (2 350 K) and in magnetic field up to 9 T. The first term is determined by a low temperature (T < 20 K) residual resistivity 7rho;0 and this term is magnetic field independent. The second term describes the electron-electron scattering in LSMO, it shows ∼ T2 dependence of resistivity up to temperature about 160 K and depends only weakly on magnetic field. The third term, proportional to 7sim; T4.5 dependence, describes a significant increase of resistivity in temperature range 160- 350 K and due to its sensitivity to applied magnetic field it is possible to approximate temperature dependence of magnetorestivity below 350 K.
