Origin of an enhanced colossal magnetoresistance effect in epitaxial Nd₀.₅₂Sr₀.₄₈MnO₃ thin films
Nd₀.₅₂Sr₀.₄₈MnO₃ films with the different thickness have been prepared by dc magnetron sputtering on LaAlO₃ (001) single-crystalline substrates. A decrease of the film thickness leads to a significant suppression of the ferromagnetic (FM) ordering and the Curie point becomes below the antiferromagne...
