Year: 2023
Frontiers in ASI in Switzerland
We presented the results of our work on artificial spin ices at “Frontiers in ASI” held in Lenzburg, Switzerland. Many thanks to the organizers for the invitation and a fantastic conference with very interesting talks and posters!
Nonlinear magnon scattering in ASI
Experiments and simulations unveiled magnon scattering in ASIs due to nonlinear processes. These were only observed in continuous magnetic films but in our recent Nature Communications, we demonstrate that similar processes are allowed by the coupling between adjacent nanoislands in ASIs. Beautiful experiments done at M. B. Jungfliesch’s group!
IEEE Magnetic School resumes
The IEEE Magnetic Summer School is restarting after a COVID hiatus this year. The event is organized this year by Vito Puliafito from Politecnico di Bari, Italy. He shared an article about his experience being both a student in 2010 and now an organizer, 13 years later!
That year, the IEEE Summer School was organized at UNO and was also attended by then grad-students Ezio Iacocca and M. Benjamin Jungfleisch, both now collaborating on artificial spin ices! Thanks Vito for the picture!
Victoria obtains scholarship to study at Duke University
Victoria will be attending Duke University in North Carolina under a scholarship to study Electrical and Computer Engineering with an emphasis in Physics. Victoria obtained Type 1 High School Scholarship through the Air Force Reserve Officer Training Corps Program.
Victoria joined the group in 2021 and developed a method to recover demag factors of stadium-shaped nanoislands from micromagnetic simulations. Her work has contributed to the development and quantitative accuracy of our general artificial spin ice model. We wish Victoria the best in her undergraduate studies!
Casey presents his work at CSURF
Casey presented a poster on “Domain-wall-induced modulational instability in ferromagnets with perpendicular anisotropy” at CSURF. This year, CSURF was held at the Colorado College. Casey did exceptionally well conveying rather fundamental and mathematically inclined research to an broad audience!
Lawrence was awarded funding for URA
Lawrence’s project “Investigating the dynamics of a macroscopic artificial spin ice” was selected for the UCCS’s Undergraduate Research Academy during summer 2023. Lawrence joins a select group of undergraduate students involved in scientific research and will participate in the workshops offered by the URA. Congratulations!
Announcement here.
APS March Meeting
Very nice talks at APS March Meeting and good company with Roopali Kukreja’s group. We presented Ghanem’s work on artificial spin ice and Iacocca gave an invited talk at the ultrafast magnetism symposium.
Ally at UCCS 3MT
Ally was selected for the finals of the 2023 UCCS Mountain Lion Grad Slam 3MT competition held on Friday, February 10. You can watch her 3-minutes presentation aimed to a broad audience and with a single slide here. Well done!
Topological magnetic monopoles
The experimental identification of topological magnetic monopoles, or hedgehogs, was published in Nature Nanotechnology. Outstanding experiments performed at COSMIC allowing for an unprecedented 10 nm resolution in the 3D-reconstructed magnetization vector of a frustrated metalattice. We were able to determine the textures’ topology directly from experimental results, identifying both hedgehogs in the bulk of the materials and “virtual” hedgehogs whose topology is bound to the material’s surfaces.
