“…the introduction of artificial pinning centers (APCs) such as BaMO 3 (M = (transition) metal, e.g. Zr, Hf, Ir, Sn) perovskites as well as double perovskites such as Ba 2 YNbO 6 (BYNO) and Ba 2 YTaO 6 (BYTO) and the mixed compound Ba 2 Y(Nb 0.5 Ta 0.5 )O 6 (BYNTO) [9][10][11][12][13][14][15][16][17][18][19][20]. These materials are known to self-assemble into c-axis oriented nanorods or platelets in the ab-plane with a typical diameter or thickness of a few nanometers.…”

REBCO based coated conductors are a viable alternative to conventional superconductors for many applications, therefore the optimization of their current carrying capacity is an ongoing process. A promising route for the increase in performance is the introduction of artificial pinning centers such as BaHfO3 nanoparticles. However, granularity still imposes a substantial performance limitation, especially in REBCO coated conductors deposited on RABiTS based templates, as the critical current density is severely reduced by moderate misalignment angles of adjacent grains. A combined study of scanning Hall probe microscopy and electron microscopy of undoped and BHO-doped YBCO films on technical templates shows that BHO-doping leads to a denser microstructure of the superconducting layer and higher global and local critical current densities. The statistical evaluation of local current maps allows for a quantification of the magnetic granularity where a reduction of granularity with increasing film thickness, doping and increasing temperature is found. In particular the dependence of granularity on the film thickness and enhanced film growth through BHO-doping shows the potential for further optimization of YBCO films on RABiTS based templates.

Dependence of the critical current on the misorientation angle in high-temperature superconductor (HTS) [001]-tilt bicrystal is theoretically examined. It’s argued that in the case of relatively small values of the bicrystal misorientation angle θ (θ ≤ 10–15°) the critical current as well as the resistive state emergence are determined by depinning of Abrikosov vortices, which are locked by c-oriented edge dislocations which form the low-angle [001]-tilt grain boundary and are aligned in a linear row along it. Dependence of the depinning critical current on the misorientation angle of bicrystal is calculated for this case and it reveals a good agreement with experimental data obtained on HTS bicrystals with low-angle [001]-tilt grain boundaries.
