Image of FIG. 1.
FIG. 1.

(a) The XRD scan for the ML film. ML and LAO denote the Bragg peaks corresponding to the film and substrate, respectively. The inset exhibits the (002) Bragg peak for ML, LCM1, and LCM2 in detail. (b) High-magnification cross-sectional HREM image of the ML film. The dashed line indicates the interface between sublayers.

FIG. 2.

a) High-magnification cross-sectional HREM image of the ML film. Dashed lines indicate the interface between sublayers. The inset shows the corresponding FFT of this HREM image. White arrows indicate the splitting of fundamental Bragg spots, manifesting the presence of two different crystal lattices. b) The selected area in the LCM2 sublayer demonstrates a modulated stripe structure with the doubled -axis lattice period. c) The corresponding FFT of this HREM image.

FIG. 3.

a) Temperature dependence of the ZFC and the FC magnetization for LCM1 (1), LCM2 (2), and ML (3) at an in-plane applied magnetic field of . Arrows indicate the Curie points. The lines are a guide to the eye. b) In-plane (open symbols) and out-of-plane (solid symbols) hysteresis loops for ML at temperature of . The inset shows the same curves in the low-field range. is the coersive magnetic field. The lines are a guide to the eye.

FIG. 4.

Temperature dependence of the resistance for LCM1 (1), LCM2 (2), and ML (3) without (solid symbols) and with (open symbols) an applied magnetic field of . Arrows indicate the temperature of the MI transition. Inset (a) displays the temperature-dependent MR ratio for the same films (open symbols correspond to ML). The lines are a guide to the eye. Inset (b) shows the temperature dependence of the AMR for ML (see text).
