Although nanoscale deformation, such as nanostrain in iron chalcogenide(FeSexTe1-x, FST) thin films, has attracted attention owing to the enhancementof general superconducting properties, including critical current density (Jc)and critical transition temperature, its formation has proven to be anextremely challenging and complex process thus far. Herein, we successfullyfabricated an epitaxial FST thin film with uniformly distributed nanostrain byinjection of a trace amount of CeO2 inside FST matrix using sequential pulsedlaser deposition. Using transmission electron microscopy and geometrical phaseanalysis, we verified that a trace amount of CeO2 injection forms nanoscalefine defects with a nanostrained region, which has a tensile strain (ezz ~0.02) along the c-axis of the FST matrix. The nanostrained FST thin filmachieves a remarkable Jc of 3.5 MA/cm2 for a self-field at 6 K and a highlyenhanced Jc under the entire magnetic field with respect to a pristine FST thinfilm.
