Abstract

The magnetic properties of single- and poly-crystalline La_(0.7)Sr_(0.3)MnO₃/Pr_(0.65)Ca_(0.35)MnO₃ multilayered (ML) films, and composite (CP) (La_(0.7)Sr_(0.3))_(0.5)(Pr_(0.65)Ca_(0.35))_(0.5)MnO₃ films, prepared by laser ablation, have been investigated in a wide temperature range. It was shown that the transformation from an incoherent to a coherent interface in the ML films leads to an enhancement of the ferromagnetic coupling between layers and to a single-phase magnetic transition. The amorphous CP films demonstrate a paramagnetic behavior of the magnetization with a sharp peak at TG?45 K, which was interpreted as the formation of Griffiths phase. A short-term annealing at 750℃ induced the complete crystallization of film, and a recovery of the ferromagnetic and the metal-insulator transitions.
