Figure 6

(a) the magnetization-temperature (MT) curves of PSMO films with different thicknesses, measured with a field of 100 Oe; (b) resistance-temperature (RT) curves at 0T and (c) Magnetoresistance (MR) of PSMO film with a magnetic field of 4T; (d) The change of χ2 with film thickness. The red dot refers to equation (1) and the blue star refers to equation (2). Refer to the text for more information.
