Crystal electric field excitations and spin dynamics in the spin-orbit coupled distorted honeycomb magnet ${\mathrm{BiErGeO}}_{5}$ (opens in new tab)

Author(s): S. Mohanty, S. Guchhait, S. S. Islam, Surya P. Patra, M. P. Saravanan, J. A. Krieger, T. J. Hicken, H. Luetkens, D. T. Adroja, Gøran J. Nilsen, M. D. Le, and R. NathHere, the authors report the magnetic properties, crystal electric field excitations, and spin dynamics of a distorted honeycomb magnet BiErGeO5. Inelastic neutron scattering and μSR experiments reveal the effect of crystal electric field leading to a Kramers doublet ground state and anisotropic interactions. Despite an...
