Suppression of Ferromagnetic Double Exchange by Vibronic Phase Segregation (2005)
Rivadulla, F., Otero-Leal, M., Espinosa, A., De Andres, A., Ramos, C., Rivas, J., ...
From Raman spectroscopy, magnetization, and thermal-expansion on the system La2/3(Ca1-xSrx)1/3MnO3, we have been able to provide a quantitative basis for the heterogeneous electronic model for...
Origin of Colossal Dielectric Response of Pr(0.6)Ca(0.4)MnO(3) (2004)
Biskup, N., De Andres, A., Martinez, J. L., Perca, C.
We report the detailed study of dielectric response of Pr(0.6)Ca(0.4)MnO(3) (PCMO), member of manganite family showing colossal magnetoresistance. Measurements have been performed on four...
Martin-Carron, L., De Andres, A., Martinez-Lope, M. J., Casais, M. T., Alonso, J. A.
We present a rationalization of the Raman spectra of orthorhombic and rhombohedral, stoichiometric and doped, manganese perovskites. In particular we study RMnO3 (R= La, Pr, Nd, Tb, Ho, Er, Y and Ca)...
Disorder induced phase segregation in La2/3Ca1/3MnO3 manganites (2002)
Garcia-Hernandez, M., Mellergard, A., Mompean, F. J., Sanchez, D., De Andres, A., McGreevy, R. L., ...
Neutron powder diffraction experiments on La2/3Ca1/3MnO3 over a broad temperature range above and below the metal-insulator transition have been analyzed beyond the Rietveld average approach by use...
