CSIC ORCID; Teresa, José María de CSIC ORCID ; Morellón, Luis CSIC ORCID; Rivadulla, Francisco | Fecha de publicación: | 2017 | Editor: | American Physical Society | Citación: | Physical Review Materials 1(7): 074407 (2017) | Resumen: | We report the fabrication of epitaxial Y3Fe5O12 (YIG) thin films on Gd3Ga5O12 (111) using a chemical solution method. Cubic YIG is a ferrimagnetic material at room temperature, with excellent magneto-optical properties, high electrical resistivity, and a very narrow ferromagnetic resonance, which makes it particularly suitable for applications in filters and resonators at microwave frequencies. But these properties depend on the precise stoichiometry and distribution of Fe3+ ions among the octahedral/tetrahedral sites of a complex structure, which hampered the production of high-quality YIG thin films by affordable chemical methods. Here we report the chemical solution synthesis of YIG thin films, with excellent chemical, crystalline, and magnetic homogeneity. The films show a very narrow ferromagnetic resonance (long spin relaxation time), comparable to that obtained from high-vacuum physical deposition methods. These results demonstrate that chemical methods can compete to develop nanometer-thick YIG films with the quality required for spintronic devices and other high-frequency applications. | Versión del editor: | https://doi.org/10.1103/PhysRevMaterials.1.074407 | URI: | http://hdl.handle.net/10261/181819 | DOI: | 10.1103/PhysRevMaterials.1.074407 | E-ISSN: | 2475-9953 |
