In a ferromagnetic nanodisk, the magnetization tends to swirl around in the plane of the disk and can point either up or down at the centre of this 'magnetic vortex'. This binary state could be ...

Another challenge is vortex damping ... they still rely on some form of traditional propulsion, whether it be fuel or electricity. In contrast, magnetic levitation technology offers a complete ...
