As is also the case for the iron-pnictides, these iron-chalcogenides exhibit a nearly quadratic temperature variation of $\\lambda(T)$ at low temperatures. The absolute value of the penetration depth in the $T \\to 0$ limit was determined for Fe$_{1.03}$(Te$_{0.63}$Se$_{0.37})$ by using an Al coating technique, giving $\\lambda(0)\\approx560 \\pm 20$ ","authors_text":"B.
