Comparative study of vortex dynamics in CaKFe4As4 and Ba0.6K0.4Fe2As2 single crystals

Wang Cheng, Hai Lin, Bing Shen +1

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 supercon…
