Coherent Magnons Driven by Photomodulated Anisotropy in Altermagnetic MnTe
Dingbin Huang, Jonathon Kruppe, Resham Babu Regmi +3
Manganese telluride () has recently emerged as a prototypical -wave altermagnet, providing an ideal platform to investigate the non-equilibrium excitations of alter…
Anisotropic Multi-Q Order in CoxTaS2
Jonathon Kruppe, Josue Rodriguez, Catherine Xu +3
The cobalt-intercalated transition metal dichalcogenide CoTaS hosts a rich landscape of magnetic phases that depend sensitively on . While the stoichiometric compound wi…
Phase control of magnons in the van der Waals antiferromagnet NiPS
Shingo Toyoda, Jonathon Kruppe, Kohtaro Yamakawa +2
We demonstrate phase control of magnons in the van der Waals antiferromagnet NiPS using optical excitation by polarized light. The sign of the coherent precession of spin ampli…
Universal spin wavepacket transport in van der Waals antiferromagnets
Yue Sun, Fanhao Meng, Changmin Lee +6
Antiferromagnets (AFMs) are promising platforms for the transmission of quantum information via magnons (the quanta of spin waves), offering advantages over ferromagnets with regar…
Electrical switching in a magnetically intercalated transition metal dichalcogenide
Nityan L. Nair, Eran Maniv, Caolan John +3
Recent advances in tuning the correlated behavior of graphene and transition-metal dichalcogenides (TMDs) have opened a new frontier in the study of many-body physics in two dimens…
Antiferromagnetic resonance and terahertz continuum in RuCl
A. Little, Liang Wu, P. Lampen-Kelley +8
We report measurements of optical absorption in the zig-zag antiferromagnet -RuCl as a function of temperature, , magnetic field, , and photon energy, in the…
