Magnetic evolution with strain via spin Hamiltonian. a Strain dependence of the in-plane (\(\left[ {1\overline 1 0} \right]\), \(\left[ {00\overline 1 } \right]\)) and out-of-plane ([110]) components of the D vector. Inset shows a schematic of the Dzyaloshinskii–Moriya interaction between two Fe cations (gold) connected by oxygens (red). b Strain dependence of the single-ion-anisotropy constant K.
