X-ray diffraction patterns for the bilayer and the pure YBCO film.
Field dependence of the critical current density. The inset shows the hysteresis loops for both samples at two different temperatures, respectively. (a) 10 K and (b) 77 K.
Temperature dependence of the normalized resistance at various applied magnetic fields. (a) The bilayer. (b) The pure YBCO.
IRLs with the zero resistance criterion of in a reduced temperature representation. Solid lines are a fit to .
Dependence of the zero temperature activation energy on applied magnetic field. The solid lines are the best fit with power law relation . The inset is the Arrhenius plot from which the values of the activation energy are obtained.
vs curves at 10 K for several LSMO films with different thicknesses. The inset shows the temperature of FC magnetization for a 40 nm thick LSMO film measured at the magnetic field of 2000 Oe, and a magnetization step is illustrated by an arrow.
