Spin-waves in GdPtBi
In the proposed experiment we intend to resolve the spin waves in GdPtBi, which is an outstanding representative of a novel class of magnets - topological antiferromagnets. In... -
Are magnetic excitations in the Yb based pyrochlores really gapless?
A recent neutron study of a powder sample attests a splayed ferromagnetic structure for Yb2Ti2O7. However in the same work the authors report gapless magnetic excitations even...
