Título: | Effect of cation disorder on structural, magnetic and dielectric properties of La2MnCoO6 double perovskite |
Autor: | Barón González, Aura J. CSIC; Frontera, Carlos CSIC ORCID; García Muñoz, Josep Lluís CSIC ORCID ; Rivas-Murias, B.; Blasco, Javier CSIC ORCID | Fecha de publicación: | 2011 | Editor: | Institute of Physics Publishing | Citación: | Journal of Physics Condensed Matter 23(49): 496003 (2011) | Resumen: | The origin of dielectric anomalies and magnetodielectric response of La2MnCoO6 has been investigated by means of ultra-high resolution synchrotron x-ray powder diffraction, neutron powder diffraction, resistivity, magnetization and dielectric measurements. The study has been performed on two different bulk samples presenting different degrees of Mn/Co order: 95 and 74%. Beside the well-known influence on magnetic properties, our results show that the main effect of disorder lies on the electrical resistivity. Bond distances clearly show Mn4+/Co2+ valence states in the well-ordered sample, while for the disordered one this picture still holds. AC resistivity data show dielectric anomalies and a small magnetodielectric effect, but impedance complex plane analyses prove that these phenomena appear at the frequencytemperature region where extrinsic effects dominate the dielectric response. © 2011 IOP Publishing Ltd. | URI: | http://hdl.handle.net/10261/52617 | DOI: | 10.1088/0953-8984/23/49/496003 | Identificadores: | doi: 10.1088/0953-8984/23/49/496003 issn: 0953-8984 e-issn: 1361-648X |
