We have studied the current-carrying capability of high quality epitaxial MgB
2 films synthesized using the hybrid physical-chemical vapor deposition technique by both transport measurement in nanobridge constrictions and magnetization measurement. An extremely high self-field critical current density Jc (0)>108 A/cm2 , approaching the theoretical depairing current of MgB2 , was observed on a 150 nm bridge, indicating an excellent current-carrying capability in these films. The magnetization measurement also showed very high Jc . [ABSTRACT FROM AUTHOR]- Published
