Geometry-controlled magnon-polaritons of double magnetic films in planar cavities

Ahmad R. T. Nugraha, Muhammad Aziz Majidi, S. Solihin

Placing two magnetic films inside one planar cavity lets their positions in the standing wave tune the strength of the collective magnon-photon interaction.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

The bilayer does not simply strengthen the magnon-photon interaction by adding magnetic material but instead enables position-dependent control of the collective bright channel.

C2weakest assumption

That the two films interact solely through the shared cavity field and their relative placement in the standing-wave pattern, with no significant direct dipolar or exchange coupling between layers.

C3one line summary

Bilayer planar cavities allow position- and symmetry-controlled magnon-polariton excitations by reorganizing bright and dark channels in macrospin and multimode regimes.
