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…

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…
