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…
Correlation-Driven Spin Reorientation via Competing Anisotropy Channels in CrPS4
Raju Baral, Harald O. Jeschke, Igor I. Mazin +3
We identify a correlation-driven mechanism for the temperature-induced spin reorientation in the quasi-one-dimensional van der Waals antiferromagnet CrPS4. Magnetic pair distributi…
Near-degenerate competing magnetic orders in EuAgAs: a tunable route to altermagnetism
Mohamed El Gazzah, Daniel Kaplan, Zachary Morgan +5
Altermagnets (AMs) have recently emerged as a distinct magnetic class bridging central features of ferromagnets (FMs) and antiferromagnets (AFMs), offering new opportunities for sp…
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…
Modeling of a twisted-Kagome HoAgGe spin ice using Reduced-Configuration-Space Search and Density Functional Theory
Gunnar F. Schwertfeger, Po-Hao Chang, Predrag Nikolic +1
The Kagome lattice is a 2D network of corner sharing triangles found in several rare earth materials resulting in a complicated and often frustrated magnetic system. In the last de…
Mystery of the 175 cm Raman Mode in MnTe Altermagnet
Bishal Thapa, K. D. Belashchenko, Igor I. Mazin
MnTe has recently attracted exceptional attention due to its well-established altermagnetism, prompting a thorough reexamination of its properties. In particular, it was found that…
