NSF funding for artificial spin ices
We are excited to announce that our project “Reconfigurable non-Hermitian and topological magnonics with interacting artificial spin ices” was awarded funding by NSF, EPMD as a standard grant. This research will deepen our understanding of topologically protected magnon modes in artificial spin ices as well as achieving substantial progress in their numerical modeling.
Ally and Kyle present at Magnonics 2022
Both Ally and Kyle presented their research progress in this international conference held in Oxnard, CA. Many interesting talks and posters. We also got to enjoy a boat trip and see dolphins!
EU-XFEL highlights our research
Our experiments were highlighted in EU-XFEL annual report 2021. Our research unambiguously demonstrates the impact of the long-range magnetic order on their ultrafast response, a key feature for any prospective application in data storage. The results of this collaborative effort are currently available on arXiv.
Ferromagnets exhibit memristance
When ferromagnets exhibit a topological texture, its dynamics may exhibit memristance when probed with a current. This effect is the dynamic analog to the anisotropic magnetoresistance (AMR) and was termed anisotropic magnetoMemristance (AMM). Fantastic collaboration with Francesco Caravelli and Cristiano Nisoli, Gia-Wei Chern, and Clodoaldo de Araujo. More details can be found in our open access publication npj Communications Physics 5, 166 (2022).
CRCW grant
We are happy to announce that our project “Nano-designed magnetic materials” was awarded funding through UCCS’s Committee on Research and Creative Works (CRCW) Faculty Seed Grant. We will investigate how magnons propagate in materials with nano-sized modifications of their material parameters. This study complements a collaborative effort with Dr. Liam O’Brien at University of Liverpool, UK, and Dr. Paul Keatley at University of Exeter, UK.
Victoria presented at CSURF
Victoria presented her work “Determination of anisotropy factors of nanomagnets” today at the 18th CSURF. Great work!
Very good experience for undergraduates at UCCS, PPCC, and AF academy.
Nanoscale solitons found
We have uncovered the nucleation of solitons at picosecond timescales in large perpendicular anisotropy nanoparticles in a recent publication in Science Advances 8, eabn0523 (2022). These nucleation processes are observed at the European XFEL via phonons that couple to the inhomogeneous magnetization dynamics of each nanoparticle. Fantastic work by the Uppsala group led by Prof. Dürr.
Ferromagnetic spin piston published
Congratulations to Mingyu Hu for publishing her work on a ferromagnetic spin piston on Phys. Rev. B. This work demonstrates how the fast dynamics in a ferromagnet subject to a spin current can have repercussions in its long-term relaxation and including the stabilization of solitons!
The paper can be found here!
More on this research can be found in Mark Hoefer’s dispersive hydrodynamics lab at CU Boulder.
McAuliffe science and engineering fair
We had a lot of fun chatting and interacting with 5th-graders about their STEM projects at McAuliffe elementary on March 9th. Prof. Kimbra Smith and I judged projects along with many other volunteers.
Roadmap on spin wave computing published
Fantastic compilation of perspectives on spin waves. Check out our contribution on spin waves in artificial spin ices with M. B. Jungfleisch. Thanks to A. Chumak, P. Kabos, and M. Wu for coordinating this effort.
