Probing the superconducting gap structure of (Li${}_{1-x}$Fe${}_x$)OHFeSe

M. Smidman, G. M. Pang, H. X. Zhou +8

We report measurements of the London penetration depth [$\Delta \lambda (T)$] of the recently discovered iron-based superconductor (Li${}_{1-x}$Fe${}_x$)OHFeSe, in order to characterize the nature…
