Figure 3: The transport properties of LPCMO.
From: Visualization of a ferromagnetic metallic edge state in manganite strips
The transport data of (a) the LPCMO film and (b) the 1.5-μm strip under magnetic fields of 0 T (dark yellow), 3 T (magenta), 5 T (cyan), 6 T (green), 7 T (red) and 9 T (black). (c,d) Magnification of the film and 1.5 μm strip transport data under 9 T at low temperatures. (e) The comparison of metal–insulator transition (MIT) temperatures between the film (black squares) and the 1.5-μm strip (red dots) derived from the cooling curve in a,b. The narrow strip exhibits higher MIT temperatures and lower resistivity than its parent film, which indicates that the edge phases are metallic.
