(a) Low-magnification cross-section STEM -contrast image of LCMO film grown on STO substrate with background oxygen; (b) high resolution STEM -contrast image near the LCMO-STO interface region; and (c) and (d) show low and high resolution STEM -contrast images, respectively, indicating the formation of twin boundaries indicated by arrows.
(a) Temperature dependence of the ZFC (open symbol) and FC (closed symbol) responses at a low applied magnetic field for LCMO films grown in different oxygen background pressures (1, 100, 200, and ). (b) Temperature dependence of the FC (closed symbol) responses at high applied magnetic fields ( and ) for LCMO films grown in different oxygen background pressures (1, 100, 200, and ). The arrows mark the FM transition temperature (either or ).
(a) The field dependence of the magnetization measured at for LCMO thin films grown under different oxygen pressures (1, 100, 200, and ); (b) the plot of the saturation magnetization and coercivity of LCMO thin films vs the oxygen pressure during growth; the dashed and doted lines are guides to the eye; and (c) the field dependence of the magnetization recorded at different temperatures for the LCMO film grown under oxygen.
