Altermagnetism could transform electronics, offering faster, more efficient, and sustainable alternatives to traditional magnetic materials.
Scientists have found an elusive third form of magnetism that could help solve a longstanding puzzle about superconductors.
Permanent magnets, the kind that keep colourful souvenirs stuck to the door of your fridge, might seem a fairly mature, well-established technology. They've been used for centuries, after all.
Magnetism to many people means the way fridge magnets stick to the side of a fridge that's made of steel. That kind of magnetic attraction is quite a strong effect. It is called ferromagnetism.
