Paper Title:
Structural and Magnetotransport Properties of Coherently Strained La2/3Ca1/3MnO3 Epitaxial Thin Films
  Abstract

Magnetotransport properties of very high quality fully strained epitaxial thin films of La2/3Ca1/3MnO3 (LCMO), grown on top of SrTiO3 (STO) (001) substrates, are analyzed. As-grown fully strained epitaxial films are ferromagnetic and metallic but exhibit depressed transport and magnetic properties (low TC and MS). Detailed analysis of the structural and magnetotransport properties after high temperature annealing processes, have revealed a progressive structural relaxation, as detected by the variation of the c/a tetragonal distortion, as the annealing temperature rises up. Nevertheless, no changes in the in-plane cell parameters are observed. Simultaneously, the magnetic transition temperature, TC, and saturation magnetisation, MS, substantially increase approaching values similar to that of bulk materials.
