Thickness-dependent vortex creep in (Y,Gd)Ba2Cu3O7−x film in a field of 1 T. a Comparison of the temperature-dependent creep rates, S(T), for the (Y,Gd)Ba2Cu3O7−x (YGdBCO) film at different thicknesses d. The error bars (standard deviation in the logarithmic fit to M(t)) are smaller than the point sizes. b Collective pinning length \(L_{\mathrm{c}}^{\mathrm{vb}}(T)\) for (Y,Gd)Ba2Cu3O7−x in the bundle regime based on Eq. (1), our experimental data for Jc (inset), and the assumption that λab(0) ≈ 140 nm is equivalent to YBa2Cu3O7−x.37,38 The calculated pinning length is too small to account for the dependence S(d) observed in a
