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…
Raman spectroscopy of the van der Waals altermagnet CoNbSe
Dushyanthini Balasundaram, Bishal Thapa, Resham Regmi +3
We investigate the influence of Co intercalation and altermagnetic order on the lattice dynamics of the layered compound CoNbSe. Polarization-resolved Raman spectroscop…
Strain continuously rotates the Néel vector in altermagnetic MnTe
Alex Liebman-Peláez, Jon Kruppe, Resham Babu Regmi +7
Altermagnetism has recently emerged as a distinct class of collinear antiferromagnets that break time-reversal symmetry, exhibiting a host of novel properties. Applied strain has a…
Relativistic and nonrelativistic spin splitting above and below the Fermi level in a -wave altermagnet
Nicholas Dale, Omar A. Ashour, Marc Vila +8
Nonrelativistic spin splitting (NRSS) challenges conventional wisdom about antiferromagnets by allowing spin-split electronic bands even in collinear orders with zero net magnetiza…
Conductivity scaling of the anomalous Hall effect in the altermagnetic semiconductor α-MnTe
Sara Bey, Shelby S. Fields, Nicholas G. Combs +22
α-MnTe is a prototypical altermagnet exhibiting a strong anomalous Hall effect (AHE), despite having a nearly vanishing magnetization. Lately, sample-to-sample variations of the a…
Anisotropy, frustration and saddle point in the twisted Kagome antiferromagnet ErPdPb
Resham Babu Regmi, Sk Jamaluddin, Y. Lee +14
The kagome lattice, with its inherent geometric frustration, provides a rich platform for exploring intriguing magnetic phenomena and topological electronic structures. In reduced-…
