Long-distance spin-transport across the Morin phase transition up to room temperature in ultra-low damping single crystals of the antiferromagnet α-Fe₂O₃

Hitherto, only circularly polarized antiferromagnetic (AFM) spin-waves (SWs) were expected to convey spin-information. Here, the authors present persistent spin-transport over long distances in the easy-plane AFM phase of hematite, α-Fe₂O₃, via linearly polarized SW pairs with ultra-low damping.

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

Tunable spin transport over long distances is demonstrated through the antiferromagnetic insulator haematite, paving the way to the development of spin-logic devices based on antiferromagnetic insulators.

Anisotropies and magnetic phase transitions in insulating antiferromagnets determined by a Spin-Hall magnetoresistance probe

Antiferromagnets are expected to be a key part of next generation electronic devices however their magnetic interactions prove difficult to access. Here, the authors demonstrate that the surface sensitive spin-Hall magnetoresistance, along with a simple analytical model, can successfully probe the internal anisotropies of the model antiferromagnet hematite (α-Fe₂O₃).

Exceptional points in oligomer chains

Open quantum systems governed by non-Hermitian dynamics provide a platform to explore PT symmetric phases. Here, a general theory is derived to describe the location of exceptional points in a 1D oligomer chain of arbitrary length.
