Figure: (a) Evolution of the total critical current, I_c (77K) with YBCO film thickness (nm) using different deposition (spin coating and ink jet printing (IJP)) for single crystalline and metallic substrates, up to 1 µm thickness. Dashed lines indicate the slopes corresponding to different critical current densities, (b) Dependence of effective anisotropy factor (g_eff) and the intrinsic anisotropy factors (determined from resistive measurements in high fields up to 65 T (g_Hc2,HF), resistive measurements (g_Hc2,res) and microwave measurements (g_MW) as a function of the nanostrain (%) for the pristine films (shown at 0.1 % nanostrain) and a set of nanocomposites with different nanostrain.
