Fecha de publicación: | 2019 | Editor: | Springer Nature | Citación: | Scientific Reports 9 (2019) | Resumen: | Platelets of strontium hexaferrite (SrFeO, SFO), up to several micrometers in width, and tens of nanometers thick have been synthesized by a hydrothermal method. They have been studied by a combination of structural and magnetic techniques, with emphasis on Mössbauer spectroscopy and X-ray absorption based-measurements including spectroscopy and microscopy on the iron-L edges and the oxygen-K edge, allowing us to establish the differences and similarities between our synthesized nanostructures and commercial powders. The Mössbauer spectra reveal a greater contribution of iron tetrahedral sites in platelets in comparison to pure bulk material. For reference, high-resolution absorption and dichroic spectra have also been measured both from the platelets and from pure bulk material. The O-K edge has been reproduced by density functional theory calculations. Out-of-plane domains were observed with 180° domain walls less than 20 nm width, in good agreement with micromagnetic simulations. | Versión del editor: | http://dx.doi.org/10.1038/s41598-019-48010-w | URI: | http://hdl.handle.net/10261/199178 | DOI: | 10.1038/s41598-019-48010-w | Identificadores: | doi: 10.1038/s41598-019-48010-w e-issn: 2045-2322 |
