Colossal magnetoresistance in manganites and related prototype devices

doi:10.1088/1674-1056/22/8/087502

摘要/Abstract

Abstract: We review colossal magnetoresistance in single phase manganites, as related to the field sensitive spin-charge interactions and phase separation; the rectifying property and negative/positive magnetoresistance in manganite/Nb:SrTiO₃ p-n junctions in relation to the special interface electronic structure; magnetoelectric coupling in manganite/ferroelectric structures that takes advantage of strain, carrier density, and magnetic field sensitivity; tunneling magnetoresistance in tunnel junctions with dielectric, ferroelectric, and organic semiconductor spacers using the fully spin polarized nature of manganites; and the effect of particle size on magnetic properties in manganite nanoparticles.

Key words: colossal magnetoresistance manganite, multiferroic heterostructure, tunnel junction, size effect
