Meissner state magneto-optical (MO) images under 5 Oe at 10 K for Fe1+yTe0.6Se0.4 annealed at 400°C for (a) 1 and (b) 3 min, respectively. (c) Local magnetic induction profiles at temperatures from 5 K to 14 K taken along the dashed lines in Figure S2a. (d) Spatial distribution of Jc/Jc(max) at 10 K for sample annealed at 400°C for 3 min.
