Abstract

Doped manganite trilayer junction provides a model system for the study of spin-dependent transport across an artificial interface between manganites. Large interface magnetoresistance is observed in manganite trilayer junctions. Further studies reveal a strongly temperature and junction-bias dependent magnetoresistance, as well as a large interaction between the spin-polarized current and the ferromagnetic moment. The physical and materials origin of these and other junction properties are discussed in this brief review.
