Long distance magnon transport in the van der Waals antiferromagnet CrPS${}_4$

Abstract

We demonstrate the potential of van der Waals magnets for spintronic applications by reporting long-distance magnon spin transport in the electrically insulating antiferromagnet chromium thiophosphate (CrPS${}_4$) with perpendicular magnetic anisotropy. We inject and detect magnon spins non-locally by Pt contacts and monitor the non-local resistance as a function of an in-plane magnetic field up to 7 Tesla. We observe a non-local resistance over distances up to at least a micron below the Neel temperature (T${}_{\mathrm{N}}$ = 38 Kelvin) close to magnetic field strengths that saturate the sublattice magnetizations.
