Abstract
We explore the physics of vortex pinning mechanism in Iron chalcogenide superconductor FeSe0.5Te0.5., via magnetization based studies. In particular we try to: (i) understand the salient features of the pinning force density (Fp) within the Dew-Hughes scenario, and (ii) compare the experimental results with the theoretical pictures of fluctuation in mean free path induced (δl) pinning and the fluctuation in superconducting order parameter induced (δTc) pinning. The results points to a δl pinning scenario in FeSe0.5Te0.5.
