Vassilios Kapaklis

Vassilios Kapaklis is a Professor in the Department of Physics and Astronomy, specifically in the Materials Physics division at Uppsala University, Sweden. He leads research in advanced magnetic nanostructures, with a strong focus on artificial spin ice, nanomagnetism, and magnetoplasmonics. His work bridges fundamental condensed matter physics with applications in nanophotonics and spintronics.

His research interests include magnetism in nanostructures, artificial spin ice systems, magnetization dynamics, magneto-optics, and nanomagnetic metamaterials. He investigates how magnetic textures and interactions at the nanoscale can be controlled using light and external fields, with implications for next-generation data storage and computing. His group employs experimental techniques such as nanofabrication, magneto-optical spectroscopy, and neutron scattering, complemented by theoretical modeling.

Recent publications reveal a strong trend in controlling magnetism via light, especially through plasmonic enhancement and ultrafast optical excitation. His team explores emergent phenomena in frustrated magnetic systems, such as thermal dynamics in artificial spin ice and long-range interactions in mesoscopic Ising chains. There is also a growing focus on ion-implantation for creating magnetic metamaterials and on structural characterization of thin films using laboratory X-ray sources.
