Spintronics fundamentally differs from traditional electronics in that, in addition to charge state, electron spins are used as a further degree of freedom, with implications in the efficiency of data storage and transfer. Spintronic systems are most often realised in [[Magnetic semiconductor|dilute magnetic semiconductors (DMS)]] and [[Heusler alloy]]s and are of particular interest in the field of [[quantum computing]] and [[neuromorphic computing]], upon which leads to integrated research requirements around [[Hyperdimensional computing|Hyperdimensional Computation]].
