Simulations of a Josephson Metamaterial Based on the S-F-S *f&sub(0) Josephson Junction / A.E.Botha, I.R.Rahmonov, [a.o.]. – Text : electronic // IEEE Transactions on Applied Superconductivity. – 2026. – Vol. 36, No. 4. – P. 7400107. – URL: https://doi.org/10.1109/TASC.2025.3635186. – Bibliogr.: 30.

We develop a discrete model for a hypothetical metamaterial consisting of an annular array of underdamped superconductor–ferromagnet–superconductor φ&sub(0) Josephson junctions. In this model, the magnetization in the F-layer is directly coupled to the Josephson current, producing φ&sub(0) phase shift that is proportional to the product of the spin-orbit coupling parameter of the ferromagnetic material and the component of magnetization perpendicular to the gradient of the asymmetric spin-orbit potential. In addition, the effective field felt by the magnetization now includes the surface current and fluxon-induced components. We show that this additional coupling can lead to the occurrence of magnetization waves that can reduce the critical current and significantly change the branching structure of the zero-field steps
