Interlayer exchange coupling in magnetic multilayers
The discovery of the exchange coupling between ferromagnetic layers separated by nonmagnetic spacer layers has stimulated a great deal of interest recently. We present a theoretical study of the interlayer coupling in magnetic multilayers using two theoretical approaches. One such approach is to …

Green function studies of the interlayer exchange coupling in magnetic multilayers
The Interlayer Exchange Coupling (IEC) of magnetic multilayers has been one of the most studied problems in condensed matter physics for the last decade. It is found that for a multilayer structure in which magnetic layers are separated by a spacer, the magnetic moments of each layer orient …

Exchange coupling and giant magnetoresistance in nickel-iron/copper multilayers
In recent years interlayer exchange coupling and giant magnetoresistance (GMR) in transition metal ferromagnet/nonmagnetic multilayers have been extensively studied. Bilinear interlayer exchange favors the collinear alignment of the magnetization of adjacent ferromagnetic layers, oscillates with …

Micromagnetic Study of Composite Media for High Density Heat Assisted Magnetic Recording
… magnetic recording (SMR) technology. The interlayer exchange coupling effects are found to affect the energy barrier during the dynamic recording process. Both the thermal effects and write temperature can be tuned by optimizing the interlayer exchange coupling effects. Further research …

Investigation of magnetic interactions in topological insulators
… forms a heterostructure and introduces magnetic exchange with the topological insulator states; while in the transitional metal ion doping, the magnetic dopants will induce magnetic order inside topological insulators. The main content and contribution of this thesis are five-fold. First and …

A study of surface roughness issues in magnetic tunnel junctions
… that the tunneling magnetoresistance and the exchange coupling are greatly modified by introducing the interface roughness into the basic Ferromagnet/Insulator/Ferromagnet structure. Experimentally, the surface roughness of the Ni80Fe20 bottom electrode is controlled by applying an rf …
