Description

The E-J characteristics of MgB2 thin film prepared by the electron beam evaporation method were investigated. The film has a fairly higher T c of 35 K and J c of 0.48 MA/cm2 at 20 K and 1 T among as-grown MgB2 films prepared by various methods. The E-J characteristics at various temperatures and magnetic fields can be described by the percolation transition model. The pinning parameters and the distribution of pinning forces of the MgB2 thin film were estimated. It was found that the MgB2 thin film has the uniform distribution of pinning forces by grain boundaries
