Magnesium reinstalls magnetism in cerium cobalt
Study shows cerium cobalt had the makings of a magnetic material after all
Researchers in the US have shown that adding magnesium to cerium cobalt (CeCo3) can transform it into a permanent magnet. The findings could help take the pressure off supplies of scarce rare-earth elements like neodymium and dysprosium, which feature in magnets in everything from earbuds and smart phones to car motors and power tools.
