Magnetization hysteresis and time decay measurements in FeSe${}_{0.50}$Te${}_{0.50}$ : Evidence for fluctuation in mean free path induced pinning

P. Das, Ajay D. Thakur, Anil K. Yadav +5

We present results of magnetic measurements relating to vortex phase diagram in a single crystal of FeSe${}_{0.5}$Te${}_{0.5}$ which displays second magnetization peak anomaly for $H \…
