Artificial intelligence is colliding with a hard physical limit: the energy and heat of today’s silicon-based chips. As ...

All ferromagnetic materials have atomic magnetic moments that are aligned parallel to each other within small regions called domains. Within these domains, the spontaneous magnetization present is ...

A tunnel junction is a device consisting of two conducting layers separated by an insulating layer. Classically, the resistance for driving current across an insulating layer is infinite; however, ...

Variable flux permanent magnet machines represent a dynamic class of electrical machines in which the air-gap magnetic flux can be actively adjusted during operation. This flexibility permits improved ...

Magnetic nanostructures have long been part of our everyday life, e.g., in the form of fast and compact data storage devices or highly sensitive sensors. A major contribution to the understanding of ...

Linear motors are synchronous motors: Current is applied to the coil to form an electromagnet. The coil then synchronizes itself to the magnetic field generated by the permanent magnets in the magnet ...
