Stress-induced magnetic domain selection reveals a conical ground state for the multiferroic phase of Mn2GeO4
J. S. White, T. Honda, R. Sibille +6
At ambient pressure (P) and below 5.5 K, olivine-type Mn2GeO4 hosts a multiferroic (MF) phase where a multicomponent, i.e., multi-k magnetic order generates spontaneous ferromagnet…
Mesoscopic Phase Coherence in a Quantum Spin Fluid
Guangyong Xu, C. Broholm, Yeong-Ah Soh +8
Mesoscopic quantum phase coherence is important because it improves the prospects for handling quantum degrees of freedom in technology. Here we show that the development of such c…
Neutron scattering from a coordination polymer quantum paramagnet
Tao Hong, M. Kenzelmann, M. M. Turnbull +7
Inelastic neutron scattering measurements are reported for a powder sample of the spin-1/2 quantum paramagnet . Magnetic neutron scattering is identified a…
Dipolar spin-waves and tunable band gap at the Dirac points in the 2D magnet ErBr3
C. Wessler, B. Roessli, K. W. Krämer +4
Topological magnon insulators constitute a growing field of research for their potential use as information carriers without heat dissipation. We report an experimental and theoret…
Distinct vortex-glass phases in YbRhSn at high and low magnetic fields
D. G. Mazzone, J. L. Gavilano, R. Sibille +3
The vortex lattice (VL) in the mixed state of the stannide superconductor YbRhSn has been studied using small-angle neutron scattering (SANS). The field dependen…
Competing Magnetic Phases on a "Kagome Staircase"
G. Lawes, M. Kenzelmann, N. Rogado +11
We present thermodynamic and neutron data on Ni_3V_2O_8, a spin-1 system on a kagome staircase. The extreme degeneracy of the kagome antiferromagnet is lifted to produce two incomm…
