Magnetoresistive and resonance properties of ultrathin films (2—12 nm) of lanthanum-strontium La$_{0.6}$Sr$_{0.2}$Mn$_{1.2}$O$_{3}$ manganites are studied. The films were deposited on LaAlO$_{3}$ single-crystalline substrate by magnetron sputtering. Characteristic features of the evolution of magnetic properties with the decrease of film thickness are specified. The electron-spin resonance studies show that the films are ferromagnetic down to a film thickness of 4 nm and retain a relatively high Curie temperature, $Т_{С}$. Based on the analysis of magnetoresistive and resonance data, it is concluded that the films with the thickness of 4 nm and less display high degree of inhomogeneity.

Key words: doped manganites, metal—insulator transition, electron spin resonance, magnetoresistance.
