An Atom-Thick Magnet: Power in a Single Layer ⚡ экспресс
Original: "Atomic scale demonstration of ferromagnetism in a single layer FeCl2 on Au(111)"
Scientists have directly observed, for the first time, how a single-atom-thick layer of iron chloride becomes a genuine magnet.

A magnet just one atom thick—it's real! A monolayer of iron chloride turns out to be a ferromagnet: it can be magnetized and remagnetized with a weak field. But tiny defects with a radius of 1.6 nm quench the magnetic signal by a factor of four, creating a natural nanopattern. A step toward ultra-dense magnetic memory.
🎯 Iron chloride is chemically very similar to common rust, but as a monolayer it transforms into a quantum magnet with amazing properties.
