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.2017http://zaguan.unizar.es/record/7567610.1103/PhysRevMaterials.1.074407http://zaguan.unizar.es/record/75676oai:zaguan.unizar.es:75676info:eu-repo/grantAgreement/ES/DGA/E26info:eu-repo/grantAgreement/ES/MEC/FPU014-02546info:eu-repo/grantAgreement/ES/MINECO/MAT2014-51982-C2info:eu-repo/grantAgreement/ES/MINECO/MAT2016-80762-Rinfo:eu-repo/grantAgreement/ES/MINECO/MAT2017-82970-C2-RPHYSICAL REVIEW MATERIALS 1, 7 (2017), 074407 [6 pp]All rights reservedhttp://www.europeana.eu/rights/rr-f/info:eu-repo/semantics/openAccess
