Pinning force data, F p, of a variety of Fe-based high-T c superconductors (11-, 111-, 122-
and 1111-type) were analyzed by means of a scaling approach based on own experimental …

The correlation in type-II superconductors between the creep rate S and the Second
Magnetization Peak (SMP) phenomenon which produces an increase in Jc, as a function of …

We performed systematic AC susceptibility and magnetic moment measurements to
investigate the vortex dynamics and pinning in $ EuRbFe_4As_4 $?--> single crystals as a …

Iron-based superconductors have become a promising candidate for high-field applications
due to their high transition temperature, ultra-high upper critical field, and low anisotropy. For …

The correlation between the appearance of a peak effect in the critical current of a
superconducting material and the presence of twin boundaries, involved in a crossover …

We investigate the vortex dynamics in two typical hole doped iron based superconductors
CaKFe 4 As 4 (CaK1144) and Ba 0.6 K 0.4 Fe 2 As 2 (BaK122) with similar superconducting …

Iron-based superconductors, just after their discovery in 2008 [1±5], have become a subject
of great interest for the scientific community and occupy one of the leading places among the …

The characteristics of Fe-based superconductors are manifested in their electronic, magnetic
properties, and pairing symmetry of the Cooper pair, but the latter remain to be explored …

Using two experimental techniques, we studied single crystals of the 122-FeAs family with
almost the same critical temperature, T c. We investigated the temperature dependence of …

Iron-based superconductors (IBSs) with ultrahigh upper critical fields and low anisotropies
