| Abstract: | This study investigated the characteristics of co-doped Sr-122 iron-based superconductors and single-crystal samples were examined using high-resolution scanning Hall probe microscopy (SHPM). In this study, we used a particular method to evaluate the formation of isolated vortices by looking at how temperature changes impact the fields' penetration depth, which we represented as λ(T). We calculated the temperature's superfluid density using this dataset. When contrasting it with the two-band superconductor predictions of the α model, the parameters generated by the fitting procedure could offer important information on the electrons' symmetry of the order parameter. In crystals made of iron, hole pockets play a major role in determining the superfluid density. Low pinning forces of field, which are many orders smaller in magnitude than values reported by other methods for identical superconducting crystals, have been estimated using vortex displacements from a perfect triangular lattice.
