Ganymede is not only Jupiter's largest moon, but also the largest in our solar system and one of the few that hosts a massive ...

Flux-switching Floquet engineering explained The Cal Poly team, led by Ian Powell, demonstrated that periodically toggling ...

Magnetic fields play an important—if sometimes underappreciated—part in planetary systems. Without a strong magnetic field, planets can end up as a barren wasteland like Mars, or they could indirectly ...

A horizontal magnetic pointer (one side painted blue, the other red) mounted on a stand between a steel plate and a copper plate. May be a horizontal dip needle or a version of Ørsted’s experiment.

Laser heating generates a temperature gradient in the MnPt layer, which induces spin currents (green arrows) that are injected into the FePt layer. These spin currents generate spin torque, which ...
