Eclipsing Kitaev: off-diagonal exchange governs the correlated high-field phases of -LiIrO
Vikram Nagarajan, Ioannis Rousochatzakis, Yuanqi Lyu +9
We report a high-field thermodynamic study of the hyperhoneycomb Kitaev material -LiIrO, using magnetotropic susceptibility to resolve its low-temperature field-angle p…
Colossal Magnetoresistance and Phonon Driven Exchange Dynamics in EuSnAs
Luke Pritchard Cairns, Kohtaro Yamakawa, Shengzhi Zhang +9
The emergence of colossal magnetoresistance in a new generation of Eu-based antiferromagnets is intriguing given stark contrasts to the archetypal perovskite manganites and…
Quantum decoherence by magnetic fluctuations in a magnetic topological insulator
Ruben Saatjian, Simon Dovrén, Kohtaro Yamakawa +3
In magnetic topological insulators, spontaneous time-reversal symmetry breaking by intrinsic magnetic order can gap the topological surface spectrum, resulting in exotic properties…
Low-Field Regime of Magnon Transport in Yttrium Iron Garnet
Hossein Taghinejad, Kohtaro Yamakawa, Xiaoxi Huang +4
Diffusive propagation of spin waves and their quanta - magnons - in the archetypal magnetic insulator yttrium iron garnet (YIG) is under a surge of research for low-power and low-l…
