Coupling Angle

Interlayer exchange coupling in transition metal multilayers has been intensively studied for more than three decades and is incorporated into almost all spintronic devices. With the current spacer layers, only collinear magnetic alignment can be reliably achieved; however, controlling the coupling angle has the potential to markedly expand the use of interlayer exchange coupling. Here, we show that the coupling angle between the magnetic moments of two ferromagnetic layers can be precisely controlled by inserting a specially designed magnetic metallic spacer layer between them. The coupling angle is controlled solely by the composition of the spacer layer. Moreover, the biquadratic coupling strength, responsible for noncollinear alignment, is larger than that of current materials. These properties allow for the fabrication and study of not yet realized magnetic structures that have the potential to improve existing spintronic devices.

Interface Effects

Possible interface effects are examined theoretically for oscillatory exchange coupling between ferromagnetic metal films separated by a nonmagnetic spacer film. It is argued that the exchange coupling is sensitive to aspects of the magnetic film’s electronic structure, and evidence from magnetic film doping experiments is described. Possible effects of interface electronic states are also explored. Finally, a suggestion for a new type of domain wall resonance experiment is made that could provide unique measures of local values of the exchange coupling strength.
