The study of the manganese oxides, widely known as manganites, that exhibit the “colossal”
magnetoresistance effect is among the main areas of research within the area of strongly …

Recent computational studies of models for manganese oxides have revealed a rich phase
diagram, which was not anticipated in early calculations in this context performed in the …

Charge-ordered phases of rare earth manganates are novel manifestations arising from
interactions between the charge carriers and phonons, giving rise to the localization of …

Neutron-powder-diffraction measurements, combined with magnetization and resistivity
data, have been carried out in the doped perovskite La 1− x Ca x MnO 3 (x= 0.47, 0.50, and …

Raman and infrared absorption spectra of Mg 1− x Al x B 2 have been collected for 0<~ x<~
0.5 in the frequency range of the phonon spectrum. The data show a remarkable …

The infrared absorption spectra of polycrystalline LaMnO 3 and CaMnO 3 measured in the
frequency range of the transverse optical phonons are reported, discussed, and compared …

THz time-domain spectroscopy was used to directly probe the low-energy (0.5–5 meV)
electrodynamics of the charge-ordered manganite Pr 0.7 Ca 0.3 MnO 3. We revealed the …

The complex impedance of a Pr 0.67 Ca 0.33 MnO 3 crystal has been measured. The
frequency dependence is studied for a wide range of temperatures (50–403 K) and is found …

The aim of the present work was to investigate how the native signal observed in the
electron paramagnetic resonance (EPR) spectrum of tooth enamel and dentin is associated …

Charge-lattice fluctuations are observed in the layered perovskite manganite LaSr 2 Mn 2 O
7 by Raman spectroscopy at temperatures as high as 340 K, and with decreasing …
