CRCW grant

Posted on by eiacocca

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

Posted on by eiacocca

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

Posted on by eiacocca

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.
