Dielectric behavior of La_1-xCa_xMnO₃ (0.4 ≤ x ≤ 0.5)

Boletín de la Sociedad Española de Cerámica y Vidrio, 2006
In this work the dielectric behavior of semiconducting La-manganites in an intermediate Ca-doping regime is studied. Ceramic samples were prepared by conventional solid-state reaction, using elemental oxides as starting reactants.

Dynamics of electronic phase separation at the laser-induced insulator-metal transition in (La_{0.6}Pr_{0.4})_{0.7}Ca_{0.3}MnO_{3}

Physical Review Research
Ultrafast optical excitations allow creating new metastable and hidden states in quantum materials. However, the fundamental material properties required to support new emergent order are largely unknown.

Estudio Mössbauer para el sistema La_0.7M_0.3Mn_1-xFe_xO_3-y (M = Pb, Sr, 0.01 ≤ X ≤ 0.3)

Boletín de la Sociedad Española de Cerámica y Vidrio, 2000
On cooling the compounds of the form La1-xMxMnO3-y (where M is divalent cation) show a large decrease in resistivity associated with a paramagnetic to ferromagnetic transition.

Effects of interaction and disorder on polarons in colossal resistance manganite Pr0.68Ca0.32MnO3 thin films

Materials Research Express, 2014
The colossal magnetoresistance effect (CMR), the drop of the electric resistance by orders of magnitude in a strong magnetic field, is a fascinating property of strongly correlated electrons in doped manganites.

A note on the different crystalline features of the EuMnO₃-based solid solutions as a function of the modifying cation nature

Boletín de la Sociedad Española de Cerámica y Vidrio, 2010
The structural properties of solid solutions based on EuMnO3, in which Eu has been substituted by divalent Ca2+ and Mn by the divalent cation Ni2+ or the variable valence cation Co2+-Co3+ have been studied by X-ray diffraction (XRD) and X-ray absorption ...

Crystalline behaviour and electrical properties of manganese perovskites substituted on A or B sites: ErMnO₃ modified by Ca and EuMnO₃ modified by Co

Boletín de la Sociedad Española de Cerámica y Vidrio, 2010
The structural and electrical features of the manganites solid solutions (Er,Ca)MnO₃ and Eu(Co,Mn)O₃, have been studied by X-ray diffraction and conductivity measurements. Powders were prepared by solid-state
