Spin Nernst magnetoresistance for magnetization study of FePS3

The magnetization of the antiferromagnetic van der Waals material FePS3 is investigated via the spin Nernst magnetoresisance (SNMR) and spin Seebeck effect (SSE). A heater and Pt detector strips are fabricated on top of a FePS3 flake which generates a temperature gradient in FePS3 and in the Pt detector strips. We are able to detect the SNMR in Pt, which is an interface effect, and detect the SSE response, which is a bulk effect. We conclude that there are uncompensated magnetic moments in FePS3 at the interface with Pt. Via the SNMR we are able to extract the real and imaginary parts of the spin mixing conductance assuming a fully uncompensated top layer. For an in-plane thermal conductivity of 10 W/(mK) and therefore a temperature gradient of 6000 K/m in Pt we find that Gr=1.9±0.06×1013ω-1m-1 and Gi=4.8±0.02×1011ω-1m-1. In addition, the temperature gradient in FePS3 generates a magnon current in FePS3 via the SSE which can be detected by the Pt detector strips. We are able to extract a magnon diffusion length of 1.3±0.5 and 0.5±0.1μm for thermally generated magnons in FePS3 for 40 and 20 nm thicknesses, respectively.</p

The spin-flop transition in the quasi two dimensional antiferromagnet MnPS3 detected via thermally generated magnon transport

We present the detection of the spin-flop transition in the antiferromagnetic van der Waals material MnPS3 via thermally generated nonlocal magnon transport using permalloy detector strips. The inverse anomalous spin Hall effect has the unique power to detect an out-of-plane spin accumulation which enables us to detect magnons with an out-of-plane spin polarization; in contrast to strips of high spin-orbit material such as Pt which only possess the spin Hall effect and are only sensitive to an in-plane spin polarization of the spin accumulation. We show that nonlocal magnon transport is able to measure the spin-flop transition in the absence of other spurious effects. Our measurements show the detection of magnons generated by the spin Seebeck effect before and after the spin-flop transition where the signal reversal of the magnon spin accumulation agrees with the OOP spin polarization carried by magnon modes before and after the SF transition
