Abstract

Pulsed laser deposition has been used for the growth of high quality YBa₂Cu₃O₇ and La_0.67Sr_0.33MnO₃ thin films and multilayers for electronic device applications. In particular, YBa₂Cu₃O₇ - (SrTiO₃, CeO₂) - La_0.67Sr_0.33MnO₃ trilayer devices were fabricated to study the supercurrent suppression by the injection of a spin-polarized quasiparticle current. Our results show that the critical current for a YBa₂Cu₃O₇ - 50 angstroms SrTiO₃ - La_0.67Sr_0.33MnO₃ device was found to decrease from 120 mA to 15 mA, for an injection current of 60 mA of spin polarized current yielding a negative current gain of approximately 1.8. 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. Once optimized, spin injection represents a new approach to fabricating superconducting transistors which could impact electronic systems for many important next generation.
