Spark plasma sintering of hydrothermally derived ultrafine Ca doped lanthanum chromite powders

Boletín de la Sociedad Española de Cerámica y Vidrio, 2006
Lanthanum chromite nano-particles, with a composition of La0.9Ca0.1CrO3 and La0.8Ca0.2CrO3, were produced by 1 h of hydrothermal reaction at 400 and 425°C respectively.

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

Anisotropia inducida por campo magnético en perovskitas de cobalto

, 2001
En este trabajo se examina la anisotropía magnética de la perovskita de cobalto Lao.7Sro.3Co03, material de alto interés tecnológico. Las medidas convencionales, hechas en la zona de alto campo, arrojan un valor de anisotropía magnética muy elevado, que contrasta con los bajos valores de campo coercitivo medidos en los ciclos de histéresis del material.

Rentgenabsorbcijas spektru kvantu ķīmiska interpretācija perovskita tipa savienojumos

, 2015
Rentgenabsorbcijas spektroskopija ir viena no aktuālām metodēm, ar kuras palīdzību mēs varam pētīt materiālus un savienojumus, iegūstot informāciju par savienojuma lokālo elektronu un atomāro struktūru. Kvantu ķīmija apskata vielas uzbūves, reakcijas spēju un ķīmisko saišu jautājumus, izmantojot kvantu mehānikas priekšstatus.

ESTUDIO DE SISTEMAS DESORDENADOS CON ESTRUCTURA DE DOBLE PEROVSKITA

, 2013
Half-metallic materials have become very attractive in view of their potential spintronic applications. In particular, the double perovskite Sr2FeMoO6 combines half-metallic ferromagnetic character with a high Curie temperature (≈ 450K). In this thesis have been studied electronic and magnetic properties of double perovskites systems.
