Claims

C1strongest claim

We show that the ferromagnetic insulators generate circular super-currents, enabling long-range magnetic interactions (LRMI), decaying in power laws. In the static case, the long-range magnetic interaction can be ferromagnetic, in contrast to previous studies showing that superconductor mediates anti-ferromagnetic interactions decaying exponentially.

C2weakest assumption

The model assumes that placing ferromagnetic insulators on the Rashba superconductor thin film generates circular supercurrents whose mediated interactions produce the claimed power-law decay and ferromagnetic sign in the static limit, without detailing the microscopic Hamiltonian, boundary conditions, or approximations used to derive the interaction.

C3one line summary

Ferromagnetic insulators on a Rashba superconductor film mediate power-law decaying long-range magnetic interactions that are ferromagnetic in the static case, unlike prior exponential anti-ferromagnetic results.
