چکیده انگلیسی
The SHI irradiation induced effects on magnetic properties of MgB2 thin films are reported. The films having thickness 300–400 nm, prepared by hybrid physical chemical vapor deposition (HPCVD) were irradiated by 200 MeV Au ion beam (Se ∼ 23 keV/nm) at the fluence 1 × 1012 ion/cm2. Interestingly, increase in the transition temperature Tc from 35.1 K to 36 K resulted after irradiation. Substantial enhancement of critical current density after irradiation was also observed because of the pinning provided by the defects created due to irradiation. The change in surface morphology due to irradiation is also studied.
