Magnetic Multilayers

摘要

Magnetic multilayers are artificially structured materials made of ultrathin films of two different mate-rials,alternately ferromagnetic and non-ferromagnetic.They exhibit new magnetic properties differ-ent from those of bulk materials.We review the magnetic properties of metallic magnetic multilayersand focus on interface magnetic anisotropy,giant magnetoresistance and interlayer couplings,whichare of great promise for applications to high density magnetic storage.
