Abstracts
We have used a three term polynomial expression to approximate electrical and magneto transport properties of epitaxial La_{0.67}Sr_{0.33}MnO_{3} (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 ρ_{0} and this term is magnetic field independent. The second term describes the electron-electron scattering in LSMO, it shows ~ T^{2} dependence of resistivity up to temperature about 160 K and depends only weakly on magnetic field. The third term, proportional to ~ T^{4.5} 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.
