Abstract The critical current densityJ c of Y1−x Ho x Ba2Cu3O7−δ (YHBCO) epitaxial thin films withx=0, 0.2, 0.4, 0.7 at various temperatures and magnetic fields has been measured magnetically. TheJ c and flux pinning density Fp values are significantly enhanced with the Ho substitute amountx with the optimal effect achieved at Ho concentration around x=0.4 in the entire measured temperature (30–77 K) and magnetic field (0–3 T) ranges. X-ray diffraction patterns have shown that the greater the lattice deformation, the higher theJ c of the films.
