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…
Spin-polarized oxygen hole states in cation deficient La(1-x)CaxMnO(3+delta)
G. Papavassiliou, M. Pissas, M. Belesi +5
When holes are doped into a Mott-Hubbard type insulator, like lightly doped manganites of the La(1-x)CaxMnO3 family, the cooperative Jahn-Teller distortions and the appearance of o…
Orbital domain state and finite size scaling in ferromagnetic insulating manganites
G. Papavassiliou, M. Belesi, M. Fardis +4
55Mn and 139La NMR measurements on a high quality single crystal of ferromagnetic (FM) La0.80Ca20MnO3 demonstrate the formation of localized Mn(3+,4+) states below 70 K, accompanie…
Phase separation and the possibility of orbital liquid states in CMR manganites. A 139La NMR study
M. Belesi, G. Papavassiliou, M. Fardis +2
139La NMR spin-lattice relaxation rate 1/T1 and rf enhancement experiments provide evidence that the low temperature regime of the ferromagnetic (FM) phase of La1-xCaxMnO3 segregat…
