Chiral Antiferromagnetism from Momentum-Space Resonance in a 2D Semiconductor
R. Okuma, T. Ikenobe, Y. Fujisawa +28
Understanding the principles governing the emergence of chiral quantum phases is a fundamental challenge, not only for uncovering new mechanisms of quantum-state formation but also…
Resolving the Magnetic Ground State and Field-Induced Transitions in Magnetic Dirac Semimetal Candidate EuMnSb
Yiu-Fung Chiu, Jian-Rui Soh, Sanjay Sharma +9
The magnetic structure of a magnetic topological semimetal EuMnSb is investigated in fields up to 30 T using polarized and unpolarized neutron diffraction, pulsed-field x-ray m…
Gapped 1/9 Magnetization Plateau in the Anisotropic Kagome Antiferromagnet Y-kapellasite
Dipranjan Chatterjee, Paul A. Goddard, Ewan R. P. Thomas +11
Fractional magnetization plateaus provide a sensitive probe of many-body spin states in frustrated quantum magnets, yet their microscopic origin in kagome antiferromagnets remains…
Vector spin polarization evolution determined in an entangled muon-fluorine system under pulsed excitation
Dipranjan Chatterjee, Benjamin M. Huddart, Hank C. H. Wu +4
A spin-polarized muon implanted into a fluoride forms a coupled F----F complex in which the muon spin and neighbouring fluorine nuclear spins become entangled. Here we apply rad…
Spinon mediation of witness spin dynamics in herbertsmithite
Hiroto Takahashi, Jack Murphy, Mitikorn Wood-Thanan +12
The kagome lattice of spin-1/2 copper atoms in herbertsmithite is conjectured to sustain a quantum spin liquid state with spinon quasiparticles. Ideally, the kagome crystal planes…
Discovery of Dynamical Heterogeneity in a Supercooled Magnetic Monopole Fluid
Jahnatta Dasini, Chaia Carroll, Hiroto Takahashi +9
Dynamical heterogeneity, in which transitory local fluctuations occur in the conformation and dynamics of constituent particles, is widely hypothesized to be essential to evolution…
Spiral Spin Liquid Noise
Hiroto Takahashi, Chun-Chih Hsu, Fabian Jerzembeck +10
An emerging concept for identification of different types of spin liquids is through the use of spontaneous spin noise. Here we develop spin noise spectroscopy for spin liquid stud…
Field-tunable Berezinskii-Kosterlitz-Thouless correlations in a Heisenberg magnet
D. Opherden, M. S. J. Tepaske, F. Bärtl +10
We report the manifestation of field-induced Berezinskii-Kosterlitz-Thouless (BKT) correlations in the weakly coupled spin-1/2 Heisenberg layers of the molecular-based bulk materia…
Local magnetism, magnetic order and spin freezing in the 'nonmetallic metal' FeCrAs
B. M. Huddart, M. T. Birch, F. L. Pratt +7
We present the results of x-ray scattering and muon-spin relaxation (SR) measurements on the iron-pnictide compound FeCrAs. Polarized non-resonant magnetic x-ray scattering…
Evidence for ground state and defect-induced spin glass behaviour in the pyrochlore osmate YOsO
N. R. Davies, C. V. Topping, H. Jacobsen +14
We present AC and DC magnetometry, heat capacity, muon spin relaxation (SR) and resonant inelastic X-ray scattering (RIXS) studies of the pyrochlore osmate YOsO. We…
