Extended Data Fig. 8. Comparison of the mechanical and functional property spectra of the new MCAs and existing commercial SMMs.

The representative commercial SMMs include silicon steel (Fe–4 wt.%Si (ref. ³⁸)), a Fe–Ni alloy (Fe–78.5 wt.%Ni (ref. ³⁸)) and a Fe–Co-based alloy (Fe–49 wt.%Co–2 wt.%V (ref. ⁶³)).
