Avoided quasiparticle decay and enhanced excitation continuum in the spin-1/2 near-Heisenberg triangular antiferromagnet Ba3CoSb2O9
David Macdougal, Stephanie Williams, Dharmalingam Prabhakaran +3
We explore the magnetic excitations of the spin-1/2 triangular antiferromagnet Ba3CoSb2O9 in its 120 degree ordered phase using single-crystal high-resolution inelastic neutron sca…
Classical spin liquid or extended critical range in h-YMnO?
Sofie Janas, Jakob Lass, Ana-Elena Tutueanu +8
Inelastic neutron experiments on the classical triangular-lattice geometrically frustrated antiferromagnet h-YMnO reveal diffuse, gapless magnetic excitations present both belo…
Resonant X-ray scattering study of diffuse magnetic scattering from the topological semimetals EuCdAs and EuCdSb
Jian-Rui Soh, Enrico Schierle, Da-Yu Yan +6
We have investigated the magnetic correlations in the candidate Weyl semimetals EuCd, (=As, Sb) by resonant elastic X-ray scattering (REXS) at the Eu edge.…
Polarizing an antiferromagnet by optical engineering of the crystal field
Ankit S. Disa, Michael Fechner, Tobia F. Nova +5
Strain engineering is widely used to manipulate the electronic and magnetic properties of complex materials. An attractive route to control magnetism with strain is provided by the…
