Magnetic excitations and interactions in the Weyl ferrimagnet NdAlSi
Chris J. Lygouras, Hung-Yu Yang, Xiaohan Yao +9
Weyl fermions can arise from time-reversal symmetry-breaking magnetism, but their impact on magnetic order is a source of ongoing research. Using high-precision neutron diffraction…
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…
Helical Spin Dynamics in Commensurate Magnets: a Study on Brochantite, CuSO(OH)
S. E. Nikitin, Tao Xie, A. Gazizulina +8
We report the direct observation of a commensurate-ordered antiferromagnetic (AFM) state but incommensurate helical spin dynamics in the natural mineral brochantite CuSO(OH…
High-temperature quantum coherence of spinons in a rare-earth spin chain
Lazar L. Kish, Andreas Weichselbaum, Daniel M. Pajerowski +6
Conventional wisdom dictates that quantum effects become unimportant at high temperatures. In magnets, when the thermal energy exceeds interactions between atomic magnetic moments,…
Quasi-two-dimensional Antiferromagnetic Spin Fluctuations in the Spin-triplet Superconductor Candidate CeRhAs
Tong Chen, Hasan Siddiquee, Zack Rehfuss +10
The tetragonal heavy-fermion superconductor CeRhAs ( K) exhibits an exceptionally high critical field of 14 T for . It under…
Magnetic structure and Ising-like antiferromagnetism in the bilayer triangular lattice compound NdZnPO
Han Ge, Tiantian Li, S. E. Nikitin +14
The complex interplay of spin frustration and quantum fluctuations in low-dimensional quantum materials leads to a variety of intriguing phenomena. This research focuses on a detai…
Cobalt-Based Pyroxenes: A New Playground for Kitaev Physics and Ising Model Realization
Pavel A. Maksimov, Alexey V. Ushakov, Andey F. Gubkin +8
Recent advances in the study of cobaltites have unveiled their potential as a promising platform for realizing Kitaev physics in honeycomb systems and the Ising model in weakly cou…
