Transforming waste heat into clean energy

Do you feel the warmth coming off your computer or cell phone? That's wasted energy radiating from the device. With automobiles, it is estimated that 60% of fuel efficiency is lost due to waste heat. Is it possible to capture ...

Controllable fast, tiny magnetic bits

For many modern technical applications, such as superconducting wires for magnetic resonance imaging, engineers want as much as possible to get rid of electrical resistance and its accompanying production of heat.

The influence of magnetic fields on thin film structures

A team of scientists from Immanuel Kant Baltic Federal University, together with their colleagues from Russia, Japan, and Australia, have studied the influence of inhomogeneous magnetic fields applied during the fabrication ...

Sending spin waves into an insulating 2-D magnet

Quantum Hall ferromagnets are among the purest magnets in the world—and one of the most difficult to study. These 2-D magnets can only be made in temperatures less than a degree above absolute zero and in high magnetic ...
