Rare-earth metals, ... Superconductors can create powerful magnetic fields, ... Along with certain precious metals and stones, rare-earth metals like neodymium are sometimes described as "conflict ...

When Swedish lieutenant-turned-rockhound Carl Axel Arrhenius picked up an odd black stone near the village of Ytterby in 1787, chemists called the ore “rare Earth.” “Rare” meant no one had ...

The special properties of rare earth magnetic materials are due to the electrons in the 4f shell. Until now, the magnetic properties of 4f electrons were considered almost impossible to control.

Recent study reveals that laser pulses can temporarily alter the magnetic properties of rare-earth elements by exciting 4f electrons. Utilizing X-ray lasers in Hamburg, researchers demonstrated ...

Rare earths are a collection of 17 lesser-known, harder-to-pronounce elements with unique luminescent and magnetic traits crucial to modern technologies. Wind turbines use dysprosium and praseodymium.

Rare earth magnets make up a very small proportion of China’s overall exports, so halting exports will not have a significant impact on the country’s domestic economy.
