摘要：
We report experimental evidence of dynamic Cooper pair breaking induced by spin-polarized quasiparticles in cuprate superconductors by studying the critical current density and quasiparticle density of states of ferromagnet-insulator-superconductor (F-I-S) heterostructures. The spin diffusion length and relaxation time are also estimated. (C) 2000 Elsevier Science B.V. All rights reserved.
