“…On the other hand, the increase in charge carrier concentration caused by Ca doping influences the T c (critical superconducting transition temperature) and the J c (critical current density) of superconductors. [14][15][16][17][18][19] As an in-depth study, sizable Y 1−x Ca x Ba 2 Cu 3 O y (Ca-YBCO) single crystals with a high doping level are essential, especially for neutron scattering experiments. The self-flux technique, as the simplest method, is widely used in the growth of single crystals.…”

“…Ever since the effect of calcium overdoping at the grain boundaries in the thin film was found, numerous studies relating to the calcium substitutions for the YBa 2 Cu 3 O z (YBCO or Y123) system have been performed to examine the physical properties of these compounds. In particular, several reports indicate that the value of charge carrier concentration ( p ) raised by calcium doping, which further influences the superconducting transition temperature ( T c ) and the critical current density ( J c ) of the polycrystalline powders, thin films, and melt‐processed bulks …”

“…To date, due to the difficulty in growing highly doped REBCO single crystals in centimeters, the top‐seeded melt‐textured growth (TSMTG) is considered to be a promising method to process large doped bulk superconductors. The effect of Ca doping has been investigated in melt‐processed YBCO and GdBCO bulk superconductors . Nevertheless, the growth of highly Ca‐doped REBCO single domain with a large size encountered two main obstacles: (1) the growth rate decreases significantly with the increasing CaCO 3 content; (2) unexpected spontaneous nucleation occurs as the amount of CaCO 3 is more than 1 wt% .…”
