Multi-Center Magnon Excitations Open the Entire Brillouin Zone to Terahertz Magnetometry of Quantum Magnets
Tobias Biesner, Seulki Roh, Aleksandar Razpopov +14
Due to the small photon momentum, optical spectroscopy commonly probes magnetic excitations only at the center of the Brillouin zone; however, there are ways to override this restr…

Giant pressure-enhancement of multiferroicity in CuBr2
J. S. Zhang, Yiqi Xie, X. Q. Liu +16
Type-II multiferroic materials, in which ferroelectric polarization is induced by inversion non-symmetric magnetic order, promise new and highly efficient multifunctional applicati…
