Magnetic gears represent a transformative approach to power transmission, utilising magnetic fields to transmit torque between rotating shafts without physical contact. This contactless operation ...

When circularly polarized light is incident perpendicular to the surface of a nano-thin film of cobalt-platinum alloy, which consists of cobalt and platinum, an opto-magnetic torque is generated (red ...

Researchers created platinum-mixed metallic magnetic nanofilms that are 5x more efficient -- the ultimate energy-saving solution. Researchers at Tohoku University have achieved a significant ...
