The Takeaway
In certain entropy-stabilized magnets, the massive disorder of the atoms surprisingly promotes the coherence of magnetic waves. Usually, messy materials destroy signals, which is why scientists try to build the most perfect crystals possible. This finding shows that the noise of the material is exactly what keeps the spin waves organized. This counterintuitive behavior opens up a new class of materials for use in spintronics and quantum computing. It means we can build high-performance tech using materials that are naturally imperfect and easier to manufacture.
From the abstract
In solids, disorder is conventionally regarded as detrimental to coherence. It typically localizes and dampens collective excitations, as exemplified by Anderson localization or the broadening of magnetic modes in systems lacking long-range order. While high-entropy materials are specifically designed to harness disorder and stabilize homogeneous mixed-phase structures that can display unique properties, this same disorder is nonetheless expected to preclude the formation of coherent magnetic ex
