Magnetization vs temperature for a single LSMO film with under a field of 500 Oe (note: the open circles are the data with a field-cool mode, while the closed ones are with a zero-field-cool mode). The magnetization is not leveled off to zero at 300 K, suggesting that the ferromagnetic transition temperature is above 300 K.
Resistivity vs for single LSMO films with (solid circles) and (open circles).
Resistivity vs for YBCO(150 nm/LSMO bilayers with , 20, 30, 40, and 50 nm from bottom to top.
Resistivity vs for the YBCO(150 nm) /LSMO(150 nm) bilayer. It indicates a transition from the metallic to the insulating phase near 150 K.
Thermoelectric power vs for YBCO (150 nm)/ LSMO bilayers with (solid circles), 10 (open circles), 30 (solid triangles), and 50 nm (solid rhombuses).
vs for YBCO (150 nm)/LSMO (50) bilayers with the magnetic field changing from zero (solid circles) to 1 T (open circles) to 3 T (down triangles).
Magnetoresistance vs magnetic field for the YBCO (150 nm)/LSMO (50 nm) bilayer at room temperature.
