Abstract

A description of critical current density and resistivity of MgB2 films was presented. The two phenomenon can be explained by the suggestion that only a fraction of the cross-sectional area of the samples carries the effective current. Measurements of ρ(T) and Jc for a number of films made by hybrid physical-chemical vapor deposition were also presented.
