Defying physics: This rare crystal cools itself using pure magnetism
SMRTR summary
Researchers discovered an unusually strong magnetocaloric effect in atacamite, a green mineral containing copper ions. When exposed to high magnetic fields, atacamite cooled to almost half its original temperature due to its unique "sawtooth chain" structure. This finding could potentially lead to the development of new materials for energy-efficient magnetic cooling technologies in the future.
