摘要

Magnetic measurements on optimally doped single crystals of BaFe2(As(1-x)Px)(2) (x approximate to 0.35) with magnetic fields applied along different crystallographic axes were performed under pressure, enabling the pressure evolution of coherence lengths and the anisotropy factor to be followed. Despite a decrease in the superconducting critical temperature, our studies reveal that the superconducting properties become more anisotropic under pressure. With appropriate scaling, we directly compare these properties with the values obtained for BaFe2(As1-xPx)(2) as a function of phosphorus content.
