Extended Data Fig. 6: Electrical-transport results for a 55° twisted CrSBr monolayer/monolayer MTJ.

a, Schematic of twisted spins. Top panel, side view; bottom panel, top view. b, Conductance versus temperature at ZF. Inset, schematic of twisted CrSBr monolayers. c, Field-orientation dependence of the tunnelling current for field oriented within the a–b plane. ±0.3 T field and 5 mV DC bias are used. d, Representatives of the two groups of ZF NV related to the a axis of the top (ϕ = 155°) and bottom (ϕ = 210°) flakes, extracted from c. e, I–V curves at ZF and 9 T. Inset, extracted ZF-TMR ratio as a function of bias, based on the ZF I–V curves. f, TMR ratio as a function of temperature. 2 mV DC bias is used. The pink curve is ZF-TMR obtained from a 45° twisted CrSBr monolayer/monolayer MTJ (Supplementary Note 2). The grey curve is TMR obtained from an untwisted bilayer MTJ (Extended Data Fig. 1) using its 1.5 T and ZF conductances.
