Low-temperature transport properties of chemical solution deposited polycrystalline La0.7Sr0.3MnO3 ferromagnetic films under a magnetic field

► La0.7Sr0.3MnO3 films were grown by a modified chemical solution deposition route. ► High quality LSMO thin films were prepared directly onto SiO2/Si substrates. ► Abnormality in resistivity of LSMO films at low temperatures was studied in detail. ► The abnormality was mainly attributed to Kondo-like spin dependent scattering.
