Observation of the spiral spin liquid in a triangular-lattice material
N. D. Andriushin, S. E. Nikitin, Ø. S. Fjellvåg +7
The spiral spin liquid (SSL) is a highly degenerate state characterized by a continuous contour or surface in reciprocal space spanned by a spiral propagation vector. Although the…
Phonon softening and atomic modulations in EuAl
A. N. Korshunov, A. S. Sukhanov, S. Gebel +6
EuAl is a rare earth intermetallic in which competing itinerant and/or indirect exchange mechanisms give rise to a complex magnetic phase diagram, including a centrosymmetric s…
Unusual magnetism of the axion-insulator candidate EuInSb
M. C. Rahn, M. N. Wilson, T. J. Hicken +16
EuInSb is a member of a family of orthorhombic nonsymmorphic rare-earth intermetallics that combines large localized magnetic moments and itinerant exchange with a low…
Hybrid Bloch-Néel spiral states in MnPtSn probed by resonant soft x-ray scattering
