Intrinsic pinning by naturally occurring correlated defects in FeSe${}_{\text{1-x}}$Te${}_{\text{x}}$ superconductors

M. L. Amigó, M. V. Ale Crivillero, D. G. Franco +7

We study the angular dependence of the dissipation in the superconducting state of FeSe and Fe(Se${}_{\text{1-x}}$Te${}_{\text{x}}$) through electrical transport measurements, using crysta…
