Structural behaviour of BiFeO3/SrRuO3 superlattices: an X-ray diffraction and Raman spectroscopy investigation

Autor: Yousfi, S., Marssi, M. El, Bouyanfif, H.

Publikováno v: Superlattices and Microstructures,(2021)

Epitaxial BiFeO3/SrRuO3 superlattices have been grown by pulsed laser deposition on a (001) oriented LaAlO3 substrate and probed by X-ray diffraction and Raman spectroscopy. To investigate the structural competition between rhombohedral BiFeO3 and or

Publikováno v: Thin Solid Films,(2021)

Dielectric response and conduction mechanism were investigated for a multiferroic BiFe$_{0.95}$Mn$_{0.05}$O$_3$ epitaxial thin film. A contribution from a thermally activated interface (0.37 eV) and the bulk of the film on the dielectric response wer
