Peculiar features of magnetic and resistive transitions in partially crystallized La0.84Na0.16MnO3 films

The present work aims to study magnetic, electric, magnetoresistance and resonance properties of partially crystallized La

thin films. Peculiar behavior resulting from the wide-range coexistence of highly conductive ferromagnetic and weakly conductive paramagnetic phases has been analyzed. Based on the results of magnetic measurements and theoretical calculations, the dependence of the volume fraction of ferromagnetic phase, V
FM
, on temperature is calculated. The V

values whereby electric resistance and magnetoresistance display maxima are determined.
