Magnetic and transport properties of La₀.₇Sr₀.₃MnO₃/Pr₀.₆₅Ca₀.₃₅MnO₃ multilayered films with different microstructure
The magnetic and transport properties of single-crystal and polycrystalline La₀.₇Sr₀.₃MnO₃/Pr₀.₆₅Ca₀.₃₅MnO₃ multilayered films are investigated in the temperature range 4.2–300 K. It is shown that the transformation from an incoherent to a coherent interface between layers leads to an enhance...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | The magnetic and transport properties of single-crystal and polycrystalline
La₀.₇Sr₀.₃MnO₃/Pr₀.₆₅Ca₀.₃₅MnO₃ multilayered films are investigated in the temperature range
4.2–300 K. It is shown that the transformation from an incoherent to a coherent interface between
layers leads to an enhancement of the ferromagnetic coupling, which is accompanied by a modification
in the temperature dependence of the resistance and by a grown negative magnetoresistance ratio
at room temperature. The influence of grain boundaries on the transport of carriers in the multilayered
films is discussed on the basis of modern theoretical approaches.
