Magnetic proximity effect in Pr₀.₅Ca₀.₅MnO₃/La₀.₇Sr₀.₃MnO₃ bilayered films
The magnetotransport properties of Pr₀.₅Ca₀.₅MnO₃/La₀.₇Sr₀.₃MnO₃ bilayer, and Pr₀.₅Ca₀.₅MnO₃ and La₀.₇Sr₀.₃MnO₃ films, deposited on LaAlO₃ (001) substrate by pulse laser deposition have been investigated. The x-ray diffraction and high-resolution electron-microscopy analysis reveals that lattice...

| description |
The magnetotransport properties of Pr₀.₅Ca₀.₅MnO₃/La₀.₇Sr₀.₃MnO₃ bilayer, and Pr₀.₅Ca₀.₅MnO₃ and
La₀.₇Sr₀.₃MnO₃ films, deposited on LaAlO₃ (001) substrate by pulse laser deposition have been investigated.
The x-ray diffraction and high-resolution electron-microscopy analysis reveals that lattice parameters for the
constituent sublayers in the bilayer are very close to that for the individual films. It was found that a ferromagnetic
transition in the La₀.₇Sr₀.₃MnO₃ sublayer significantly modifies the magnetotransport properties of the
Pr₀.₅Ca₀.₅MnO₃ constituent sublayer, owing to occurrence of a magnetic proximity effect. The main evidences
for this effect are an appearance of the exchange bias interaction between the constituent sublayers; a localizedto-itinerant
crossover in the system of polarized electrons, which results in formation of the Griffiths-like ferromagnetic
state; and an unusual polaron transport of carriers. The experimental results have been analyzed within
the framework of modern theoretical approaches.
