FIG. 1.

(Color online) Jc as a function of field for H//c at different temperatures.

FIG. 2.

(Color online) Jc as a function of field for H//c (open symbols) and H⊥ c (filled symbols).

FIG. 3.

(Color online) Angular dependence of the normalized critical current density at various temperature and fields. A large peak is visible for H//c indicating the presence of a strong anisotropic pinning mechanism.

FIG. 4.

(Color online) Activation energy for vortex motion U0 versus inverse magnetic field 1/H. The data of the film deposited onto SrTiO3 (red square symbols) extracted from the Arrhenius plot of resistance (shown in the inset) can be fitted with a single exponent α ≈ 0.2 in the whole magnetic field range, oppositely to the case of a film deposited on LaAlO3 (blue round symbols). The latter film is similar to those whose Jc is presented in Ref. 7. Also, 122 and 1111 iron-based superconducting films reported in literature exhibit U0 which is not described by a single exponent power law.19–22

FIG. 5.

(Color online) High density of randomly distributed nanorods, originating from the lattice mismatch with the SrTiO3 substrate. These defects have a diameter of 2 nm, which matches very well the coherence length.
