Varun published in PRB

Congratulations to Varun who just published his first paper in Phys. Rev. B 111, 184412 (2025). In this work, we investigated the effect of the nanomagnet’s shape on the ferromagnetic resonance of artificial spin ices.

These results demonstrate the relevance of edge modes as nanomagnets transition from a rectangular (P=0) to an elliptical (P-=1) cross section.

Special thanks to P. Schiffer who introduced us to this topic. Their paper on the effect of shape on the magnetization states is a companion article at Phys. Rev. B 111, 184420 (2024)
