(a) Temperature dependence of self-field Jc for sample S10 and S30 compared with data on Co-doped Ba122 taken from ref. 27. The relatively large Jc values indicate bulk SC for the strained films. Bulk Tc,0 was taken for normalizing the data. The error bars are caused by the uncertainty in the film thickness due to the surface roughness (minimal and maximal size of Ba122 layer thickness). (b) and (c) provide Jc(B) data for samples S10 and S30, respectively.
