Our first paper of 2023 was selected as Editors' Suggestion in PRB!
It demonstrates a remote sensing scheme where the superconducting transition can be monitored via the change in anisotropy field across a remote ferromagnetic insulator.

Many thanks to Frank Schlawin and Hans Huebl for the thorough scrutiny and discussion, and Foteini Oikonomou for making everything run smoothly. Congrats on the nice work, Andreas! Photo: K-E. Sødahl
We predict that the superconductor can be probed over long distances via an induced anisotropy field over a ferromagnetic insulator in our new preprint:
