> The researchers thereby arrived quickly at the most promising compounds without analysing every single combination of the three elements. The researchers synthesised the most promising candidate, and found good agreement with their predictions. ‘I think this is the first demonstration of a rare-earth free magnet that does have high anisotropy,’ says Wang, ‘but the real magnet will be a lot more complicated than a single crystal, so this just opens the door and there’s a lot of work to be done.’
