Georgetown University researchers have discovered a new class of strong magnets that do not rely on rare-earth or precious ...

A new framework for understanding the nonmonotonic temperature dependence and sign reversal of the chirality-related ...

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 ...

Free electron X-ray lasers deliver intense ultrashort pulses of x-rays, which can be used to image nanometer-scale objects in a single shot. When the x-ray wavelength is tuned to an electronic ...

Artificial intelligence is colliding with a hard physical limit: the energy and heat of conventional chips. As models scale into the trillions of parameters, simply throwing more silicon and ...

Study demonstrates a chiral fermionic valve that separates handedness via quantum geometry, enabling transport and ...

Tests of glass samples gathered on Apollo missions show magnetization may result from impacts of objects like meteors, not as a result of magnetization from the presence of a magnetic shield. In 2024, ...

In 2024, a new age of space exploration will begin when NASA sends astronauts to the moon as part of their Artemis mission, a follow-up to the Apollo missions of the 1960s and 1970s. Some of the ...

How Does Superheating Reduce the Magnetism of Magnets? To understand how temperature might affect a magnet, you need to look at the atomic structure of the elements it is made of. Magnets are made of ...
