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…
The metal-insulator transition of the ferromagnetic La7/8Sr1/8MnO3 probed by spin waves: a 2D stripe superstructure
M. Hennion, F. Moussa, P. Lehouelleur +2
We report a study of spin waves in hole-doped ferromagnetic La7/8Sr1/8MnO3, in the metallic state (165K) below TC (181K) and through the puzzling metal-insulator transition which o…
Nuclear Magnetic Resonance as a probe of nanometre-size orbital textures in magnetic transition metal oxides
G. Papavassiliou, M. Pissas, M. Belesi +7
The study of strong electron correlations in transition metal oxides with modern microscopy and diffraction techniques unveiled a fascinating world of nanosize textures in the spin…
Confined spin waves reveal an assembly of nanosize domains in ferromagnetic La(1-x)CaxMnO3 (x=0.17,0.2)
M. Hennion, F. Moussa, P. Lehouelleur +4
We report a study of spin-waves in ferromagnetic LaCaMnO, at concentrations x=0.17 and x=0.2 very close to the metallic transition (x=0.225). Below T, in the…
Antiferromagnetic ordering in a 90 K copper oxide superconductor
J. A. Hodges, Y. Sidis, P. Bourges +3
Using elastic neutron scattering, we evidence a commensurate antiferromagnetic Cu(2) order (AF) in the superconducting (SC) high- cuprate $\rm YBa_2(Cu_{1-y}Co_y)_3O_{7+δ}…
