Classical Kitaev model in a magnetic field
Paul A. McClarty, Roderich Moessner, Karlo Penc +1
Motivated by experiments on spin-orbit coupled magnets with Kitaev exchange in magnetic fields, we present an analysis of the classical Kitaev honeycomb model in the presence of a…
Intrinsic quantum disorder in Yb2Ti2O7 and the quantum S=1/2 pyrochlore phase diagram
Shang-Shun Zhang, Anish Bhardwaj, S. M. Koohpayeh +4
We present an experimental and theoretical study of the anisotropic pyrochlore phase diagram. Inelastic field-dependent neutron scattering on YbTiO shows intrinsic broa…
Altermagnetism revealed by polarized neutrons in MnF
Quentin Faure, Dalila Bounoua, Victor Balédent +6
Motivated by possible spintronics applications in antiferromagnets, it was recently observed that symmetry admits magnets that combine attractive features of both ferromagnets and…
Collinear Altermagnets and their Landau Theories
Hana Schiff, Paul McClarty, Jeffrey G. Rau +1
Altermagnets exhibit spontaneously spin-split electronic bands in the zero spin-orbit coupling (SOC) limit arising from the presence of collinear compensated magnetic order. The di…
Magnon Spectra of Cuprates beyond Spin Wave Theory
Jiahui Bao, Matthias Gohlke, Jeffrey G. Rau +1
The usual starting point for understanding magnons in cuprate antiferromagnets such as LaCuO is a spin model incorporating cyclic exchange, which descends from a one-band H…
Observing Altermagnetism using Polarized Neutrons
P. A. McClarty, A. Gukasov, J. G. Rau
Altermagnets are colinear compensated magnets whose magnetic symmetries at zero spin-orbit coupling break spin degeneracy leading to spin-split electronic and magnonic bands that r…
