Graphene spin valve: An angle sensor
TLDR
In this paper, the angle dependent magnetoresistance (MR) in a spin valve for different orientations of applied magnetic field (B) has been investigated and the switching points of spin valve signals show a clear shift towards higher B for each increasing angle of the applied field, thus sensing the response for respective orientation of the magnetic field.About:Â
