Stabilization of an orthorhombic phase in LiMn2O4 by means of high pressure. (2005)

Paolone, A., Sacchetti, A., Postorino, P., Cantelli, R., Congeduti, A., Rousse, G., ...

LiMn2O4 is considered a promising material for the Li ion battery technology. Moreover, this material has been largely investigated in the last few years because it presents a charge order transition...

High pressure x-ray absorption spectroscopy at lower energy in the dispersive mode: application to Ce and FePO4. (2005)

Itié, J.P., Baudelet, F., Congeduti, A., Couzinet, B., Farges, F., Polian, A.

X-ray absorption spectroscopy (XAS) using a diamond anvil cell has been extended to lower energies (below 6 keV) thanks to smaller diamond anvils and to a new acquisition set-up on the energy...

EXAFS Study of Pressure-Induced Phase Transition in SrWO4. (2005)

Kuzmin, A., Kalendarev, R., Purans, J., Itié, J. P., Baudelet, F., Congeduti, A., ...

Pressure-induced scheelite-to-wolframite structural phase transition in SrWO4 was studied using two complementary techniques – X-ray absorption spectroscopy and X-ray diffraction (XRD). In situ XRD...

Pressure-tuning of the electron-phonon coupling: the insulator to metal transition in manganites (2003)

Postorino, P., Congeduti, A., Dore, P., Gorelli, F. A., Ulivi, L., Sacchetti, A., ...

A comprehensive understanding of the physical origin of the unique magnetic and transport properties of A_(1-x)A'^xMnO_3 manganites (A = trivalent rare-earth and A' = divalent alkali-earth metal) is...

Effect of Al doping on the optical phonon spectrum in Mg(1-x)Al(x)B(2) (2001)

Postorino, P., Congeduti, A., Dore, P., Nucara, A., Bianconi, A., Di Castro, D., ...

Raman and infrared absorption spectra of Mg(1-x)Al(x)B(2) have been collected for 0

Anomalous High Pressure Dependence of the Jahn-Teller Phonon in La0.75Ca0.25MnO3 (2001)

Congeduti, A, Postorino, P, Caramagno, E, Nardone, M, Kumar, A, Sarma, DD

Raman spectra of La0.75Ca0.25MnO3 have been collected for the first time over a wide pressure range 0 14 GPa using a diamond anvil cell. The frequency range explored 200 1100 cm21 and the very good...
