Fig. 4: TMR in AMFTJs with noncolinear AFM electrodes due to Néel spin currents.
a Schematics of staggered Néel spin currents in a collinear antiferromagnet with strong intra-sublattice coupling. b AFMTJ with Néel spin currents that can be qualitatively considered as two MTJs connected in parallel. c \(\hat{P}\hat{T}\) symmetric 2D A-type AFM metal Fe4GeTe2 that supports Néel spin currents. d Lateral AFMTJ with sizable TMR despite the spin-degenerate electronic structure of Fe4GeTe2 electrodes. The figures are reprinted from ref. 11. with permission.
