摘要：

The measurements on strong quasiparticle injection through a tunnel barrier into a high-T(c) YBa2Cu3O7 (YBCO) bicrystal film/junction or a YBCO film are presented. With an increase of tunnel injection current, both the Josephson and film critical currents decreased and were driven to zero to yield the normal state at a certain critical injection current density which ranged 20-140 A/cm2 for 70 to a few 100 mV voltage bias. The results are qualitatively different from simple heating phenomenon and reflect nonthermal nature of high-T(c) superconductors under injection.
