Exchange coupling and giant magnetoresistance in nickel-iron/copper multilayers
Abstract
dc:descriptionIn 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 the thickness of the non-magnetic spacer layer, and has been observed in a large number of magnetic multilayer and trilayer systems. Biquadratic exchange favors the perpendicular alignment of the magnetization of adjacent ferromagnetic layers and has been observed in several magnetic multilayer and trilayer systems. Unlike bilinear exchange, the origins of biquadratic exchange are uncertain. Generally, biquadratic exchange is significantly weaker than bilinear exchange.
