Abstract

Trilayer YBa2Cu3O7-δ/(SrTiO3, CeO2)/La0.67Sr0.33MnO3-δ devices have been fabricated for the study of supercurrent suppression due to the injection of spin-polarized quasiparticle current. The critical current for a YBa2Cu3O7-δ/100 Å SrTiO3/La0.67Sr0.33MnO3-δ device was found to decrease from 118 mA to 12.6 mA, for an injection current of 60 mA. The effect of film microstructure on the critical current suppression was investigated. Defects in the SrTiO3 and CeO2 layers were found to control the device properties.
