Fig. 9: J _c (H//c) and F _p (H//c) at 4.2 K for previous record performing films with present results (red squares) superimposed.

a J _c versus H at 4.2 K for the following films: Miura et al., highly over-doped (Y,Gd)Ba₂Cu_2.3O_X + BHO film made using CSD⁵³, rotated dark green triangles, Stangl et al.^51,52, overdoped YBCO film made via PLD, brown circles; Xu et al.⁵⁶, 15%Zr doped (Y_0.6Gd_0.6)Ba₂Cu_2.3O_X film made via MOCVD, data at 4.2 K, purple diamonds; Majkic et al.⁵⁷, 15%Zr doped REBCO film made via MOCVD and reported in Fig. 8 of ref. ⁵³, data at 4.2 K, dark blue triangles; and Goyal et al.⁴⁶, YBCO + 4 vol%BZO via PLD, data at 5 K, light green triangles; Goyal et al.⁴⁶, YBCO + 2 vol%BZO via PLD, data at 5 K, inverted turquoise blue triangles. b F _p versus H at 4.2 K for same films as in a. In previous work, the highest F _p was for Miura et al., with the F _p ~ 2.8TN/m³ at 7 T. Stangl et al. reported on a YBa₂Cu_3.0O_X film with no added pinning centers and hence had a lower F _p between applied fields of 3–5 T than several other films shown on the plot.
