Estudio desde primeros principios de transiciones de fase asociados a rotaciones de los octaedros en perovskitas [PDF]

Perovskites are a class of crystals of chemical formula ABX₃ that can be visualized as a network of BX₆ octahedra connected by the vertices, with the A-cation sitting in the interstices between octahedra. These crystals have an ideal cubic structure that

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.

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 ...

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.
