Magnetic properties and excitation spectrum of the S = 1/2 three-legged spin ladder, LiMoOP2O7
Aly H Abdeldaim, Alexander A. Tsirlin, Jacques Ollivier +4
We report a comprehensive experimental study including density functional theory calculations detailing the magnetic ground state of the Mo pyrophosphate, LiMoOP2O…
Observation of Switchable Chiral Magnons in an Altermagnet
Zheyuan Liu, Hodaka Kikuchi, Zijun Wei +8
Chiral magnons, the quanta of handed spin waves, transport spin angular momentum without energy loss due to Joule heating. The recently discovered altermagnets were proposed to hos…
Crystal electric field excitations and spin dynamics in a spin-orbit coupled distorted honeycomb magnet BiErGeO
S. Mohanty, S. Guchhait, S. S. Islam +9
The magnetic properties and crystal electric field (CEF) scheme of BiErGeO are investigated via magnetization, heat capacity, muon spin relaxation (muSR), and inelastic neutron…
Revisiting the magnetic ground states of RECo permanent magnets
F. de Almeida Passos, G. J. Nilsen, R. Dankelman +5
In light of recent improvements in the theory of rare earth magnets, as well as the availability of improved neutron powder diffraction data on these materials, we revisit the magn…
Polarized Neutrons at ISIS: Recent Developments And Highlights
Polly Mitchell, Holly I. Barnfield, Mark Devonport +4
We present two recent projects which aim to improve the performance of polarized neutron scattering experiments using hyperpolarized spin filters at ISIS. The first is the…
Kitaev Interactions Through an Extended Superexchange Pathway in the jeff = 1/2 Ru3+ Honeycomb Magnet, RuP3SiO11
Aly H. Abdeldaim, Hlynur Gretarsson, Sarah J. Day +7
Magnetic materials are composed of the simple building blocks of magnetic moments on a crystal lattice that interact via magnetic exchange. Yet from this simplicity emerges a remar…
Temperature dependence of the anomaly in the excitation spectrum of the 2D quantum Heisenberg antiferromagnet
W. Wan, N. B. Christensen, A. W. Sandvik +7
It is well established that in the low-temperature limit, the two-dimensional quantum Heisenberg antiferromagnet on a square lattice (2DQHAFSL) exhibits an anomaly in its spectrum…
Putative spin-nematic phase in BaCdVO(PO)
M. Skoulatos, F. Rucker, G. J. Nilsen +14
We report neutron scattering and AC magnetic susceptibility measurements of the 2D spin-1/2 frustrated magnet BaCdVO(PO). At temperatures well below $T_{\sf N}\approx 1…
Role of defects in determining the magnetic ground state of ytterbium titanate
D. F. Bowman, E. Cemal, T. Lehner +11
Pyrochlore systems are ideally suited to the exploration of geometrical frustration in three dimensions, and their rich phenomenology encompasses topological order and fractional e…
Classical Spin Nematic Transition in LiGaInCrO
R. Wawrzyńczak, Y. Tanaka, M. Yoshida +6
We present the results of a combined Li NMR and diffraction study on LiGaInCrO, a member of LiGaInCrO "breathing" pyrochlore fam…
Absence of long range order in the frustrated magnet SrDyO due to trapped defects from a dimensionality crossover
N. Gauthier, A. Fennell, B. Prévost +12
Magnetic frustration and low dimensionality can prevent long range magnetic order and lead to exotic correlated ground states. SrDyO consists of magnetic Dy ions for…
Breathing Pyrochlore Lattice Realized in A-Site Ordered Spinel Oxides LiGaCr4O8 and LiInCr4O8
Yoshihiko Okamoto, Gøran J. Nilsen, J. Paul Attfield +1
A unique type of frustrated lattice is found in two A-site ordered spinel oxides, LiGaCr4O8 and LiInCr4O8. Because of the large size mismatch between Li+ and Ga3+/In3+ ions at the…
