Papavassiliou, G., Pissas, M., Belesi, M., Fardis, M., Stamopoulos, D., Kontos, A., ...
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, charge, and...
Spin-polarized oxygen hole states in cation deficient La(1-x)CaxMnO(3+delta) (2003)
Papavassiliou, G., Pissas, M., Belesi, M., Fardis, M., Ansermet, J. P., Carlier, D., ...
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 orbital ordering...
Orbital domain state and finite size scaling in ferromagnetic insulating manganites (2002)
Papavassiliou, G., Belesi, M., Fardis, M., Pissas, M., Dolinsek, J., Dimitropoulos, C., ...
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, accompanied with strong...
Belesi, M., Papavassiliou, G., Fardis, M., Kallias, G., Dimitropoulos, C.
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 segregates into...
Shaqfeh, E. S., Moln, P., Lele, S., Dubief, Y., Dimitropoulos, C.
We present numerical simulations of turbulent drag reduction in wall-bounded flows by additives. The bulk of the work concentrates on polymer additives. A multiscale approach was used to study the...
Thermal Cycling and Growth of the Martensite Studied by NMR in an Ag-Cd Alloy (1995)
Scherrer, P., Rubini, S., Dimitropoulos, C., Borsa, F.
113Cd NMR measurements in two Ag-Cd samples cycled between room temperature and temperatures below Ms are presented. The growth curve of the martensite on cooling presents a discontinuity in the...

NMR TECHNIQUES APPLIED TO MARTENSITIC TRANSFORMATION (1991)
Dimitropoulos, C., Borsa, F., Rubini, S., Gotthardt, R.
The NMR parameters which should be measured in order to obtain microscopic information about Martensitic Phase Transformations are briefly discussed. Recent results of 27Al and 63 CU NMR are...
