Tunable long-distance spin transport in a crystalline antiferromagnetic iron oxide

Authors of a recent Nature letter demonstrate that this simple antiferromagnetic insulator (haematite) conveys spin information order over distances of more than tens of micrometres. This mechanism transports spins as efficiently as the most promising complex ferromagnets. Their result could pave the way to electrically tunable, ultrafast, low-power, antiferromagnetic-insulator-based spin-logic devices that operate without magnetic fields at room temperature.
