The Magnetoelastic Distortion of Multiferroic BiFeO in the Canted Antiferromagnetic State
Toomas Rõõm, Johan Viirok, Laur Peedu +17
Using THz spectroscopy, we show that the spin-wave spectrum of multiferroic BiFeO in its high-field canted antiferromagnetic state is well described by a spin model that violat…
Duality and domain wall dynamics in a twisted Kitaev chain
C. M. Morris, Nisheeta Desai, J. Viirok +9
The Ising chain in transverse field is a paradigmatic model for a host of physical phenomena, including spontaneous symmetry breaking, topological defects, quantum criticality, and…
Magnetic anisotropy and exchange paths for octa- and tetrahedrally coordinated Mn ions in the honeycomb multiferroic MnMoO
D. Szaller, K. Szász, S. Bordács +11
We investigated the static and dynamic magnetic properties of the polar ferrimagnet MnMoO in three magnetically ordered phases via magnetization, magnetic torque, and T…
Experimental Observation of Quantum Many-Body Excitations of Symmetry in the Ising Chain Ferromagnet CoNbO
Kirill Amelin, Johannes Engelmayer, Johan Viirok +4
Close to the quantum critical point of the transverse-field Ising spin-chain model, an exotic dynamic spectrum was predicted to emerge upon a perturbative longitudinal field. The d…
