Abstract
We use magnetic force microscopy (MFM) to characterize superconductivity across the superconducting dome in BaFe2(As1−xPx)2, a pnictide with a peak in the penetration depth (λab) at optimal doping (xopt), as shown in sample-wide measurements. Our local measurements show a peak at xopt and a TC vs λab−2 dependence similar on both sides of xopt. Near the underdoped edge of the dome λab increases sharply, suggesting that superconductivity competes with another phase. Indeed, MFM vortex imaging shows correlated defects parallel to twin boundaries only in underdoped samples and not for x≥xopt.
