Abstract

Advances in thin film deposition techniques have made it possible to produce heterostructures of high-temperature superconducting compounds and manganite perovskites. The latter exhibit the phenomenon of colossal magnetoresistance (CMR). The half-metallic character of the CMR compounds results in their carriers being spin polarized. Experiments with these heterostructures have demonstrated that the injection of spin-polarized carriers into high-temperature superconductors results in a reduction of parameters such as the critical current and critical temperature. The experimental situation is reviewed, and open questions are identified.
