Dynamic magnetic phase transition induced by parametric magnon pumping
Jun-Yi Shan, Jonathan B. Curtis, Mingyao Guo +7
Uncovering pathways to optically drive magnetic order-disorder transitions on ultrashort timescales can lead to the realization of novel out-of-equilibrium quantum phenomena. A lon…
Dzyaloshinskii-Moriya interaction and spin re-orientation transition in the frustrated kagome lattice antiferromagnet
K. Matan, B. M. Bartlett, J. S. Helton +10
Magnetization, specific heat, and neutron scattering measurements were performed to study a magnetic transition in jarosite, a spin-5/2 kagome lattice antiferromagnet. When a magne…
Polarized neutron scattering studies of the kagome lattice antiferromagnet KFe3(OH)6(SO4)2
K. Matan, J. S. Helton, D. Grohol +4
We report polarized neutron scattering studies of spin-wave excitations and spin fluctuations in the S=5/2 kagome lattice antiferromagnet KFe3(OH)6(SO4)2 (jarosite). Inelastic pola…
Pressure-induced Spin-Peierls to Incommensurate Charge-Density-Wave Transition in the Ground State of TiOCl
A. Prodi, J. S. Helton, Yejun Feng +1
The ground state of the spin-Peierls system TiOCl was probed using synchrotron x-ray diffraction on a single-crystal sample at T = 6 K. We tracked the evolution of the structural s…
