Magnetic Mode Coupling in Hyperbolic Bowtie Meta-Antennas (2023)
Journal Article
Ebrahimi, S., Muravitskaya, A., Adawi, A. M., Baudrion, A. L., Adam, P. M., & Bouillard, J. S. G. (2023). Magnetic Mode Coupling in Hyperbolic Bowtie Meta-Antennas. Journal of Physical Chemistry Letters, 14(35), 7824-7832. https://doi.org/10.1021/acs.jpclett.3c01620

Hyperbolic metaparticles have emerged as the next step in metamaterial applications, providing tunable electromagnetic properties on demand. However, coupling of optical modes in hyperbolic meta-antennas has not been explored. Here, we present in det... Read More about Magnetic Mode Coupling in Hyperbolic Bowtie Meta-Antennas.

Simulations of magnetization reversal in FM/AFM bilayers with THz frequency pulses (2023)
Journal Article
Hirst, J., Ruta, S., Jackson, J., & Ostler, T. (2023). Simulations of magnetization reversal in FM/AFM bilayers with THz frequency pulses. Scientific reports, 13(1), Article 12270. https://doi.org/10.1038/s41598-023-39175-6

It is widely known that antiferromagnets (AFMs) display a high frequency response in the terahertz (THz) range, which opens up the possibility for ultrafast control of their magnetization for next generation data storage and processing applications....

Topological magnetic monopoles (TMMs), also known as hedgehogs or Bloch points, are three-dimensional (3D) nonlocal spin textures that are robust to thermal and quantum fluctuations due to the topology protection1-4. Although TMMs have been observed... Read More about Three-dimensional topological magnetic monopoles and their interactions in a ferromagnetic meta-lattice.
