  • Figure 2

    (Color online) Resistivity vs. temperature measurements of LPCMO nanowires. (a)-(h) The resistivity vs. temperature curves under cooling and warming. Black, red, green, blue, purple, and orange correspond to the different external magnetic fields applied, and being 0, 1, 2, 3, 5, and 9 T, respectively. (i) The resistivity of the 400 nm nanowire under cooling and warming conditions in a 2 T magnetic field exhibiting clear thermal hysteresis and resistivity jump behaviors. (j) The resistivity of the 50 nm nanowire under cooling and warming conditions in at 5 T magnetic field. No thermal hysteresis and resistivity jumps are observed. Blue and red in (i) and (j) correspond to cooling and warming processes, respectively.

    (Color online) Resistivity vs. external magnetic field behavior at different temperatures. (a)-(d) correspond to temperatures of 160, 110, 60, and 10 K. Black, red, blue, green, and purple correspond to different widths of nanowires, corresponding to 400, 300, 200, 100, and 50 nm, respectively.

(a) AFM image of the morphology of the selected nanowires (left to right: width=1 μm, 500 nm, 200 nm, and 100 nm). (b)-(h) MFM images of the four wires of differing widths in different applied magnetic fields. Red color refers to the FMM phase and blue color refers to the nonmagnetic phase.
