Quantized spin waves in the metallic state of magnetoresistive manganites
S. Petit, M. Hennion, F. Moussa +4
High resolution spin waves measurements have been carried out in ferromagnetic (F) La(1-x)(Sr,Ca)xMnO3 with x(Sr)=0.15, 0.175, 0.2, 0.3 and x(Ca)=0.3. In all q-directions, close to…

Hybrid Goldstone modes in multiferroics
S. Pailhes, X. Fabreges, L. P. Regnault +5
By using polarized inelastic neutron scattering measurements, we show that the spin-lattice quantum entanglement in mutliferroics results in hybrid elementary excitations, involvin…
