Description
Aleš Cahlík and co-authors show that a single layer of nickel bromide can hold magnetic and electric order at the same time. Their 2026 study follows a like find in nickel iodide, a sister material. The open question was whether the effect is a one-off or a trait that chemists can tune across the family.
With a fine scanning probe, the team pictured patches of electric order in the layer, atom by atom. They then flipped the magnetic order with an electric field and, in turn, crushed the electric order with a magnet. Both tricks worked, which proves the two orders are linked. The state in the bromide proved less sturdy than in the iodide, in line with weaker links between atoms.
