- The magnetoresistance anisotropy of ultrathin La$\text{}_{0.83}$Sr$\text{}_{0.17}$Mn O$\text{}_{3}$ films deposited on NdGaO$\text{}_{3}$ substrate by metalorganic chemical vapour deposition technique was investigated. The electric-field-induced resistance change was studied up to electric fields of 10 kV/cm using ns duration electrical pulses. It was found that in ultrathin (< 10 nm) and thin (< 50 nm) films the origin of electric-field-induced resistance change is thermal. However, the films with thicknesses of about 20 nm, exhibit negative electric-field-induced resistance change, having a pure electronic nature. This effect is explained in terms of two-layer systems with imperfections located at the interface between the layers.
