For spintronics, heterostructures of ferromagnetic insulators and nonmagnetic conductors are very interesting as e.g. the spin Seebeck or the spin Hall effect can be studied. Pt/Yttrium Iron Garnet (Y3Fe5O12,YIG) is currently in focus [1]. Only recently, it has been found that the quality of the Pt/YIG interface is crucial [2-4].
We performed a detailed growth study of Pt on YIG single crystals. The samples have been studied in-situ by Auger-Electron-Spectroscopy and Reflection High/Low Energy Electron Diffraction and ex-situ by X-ray reflectivity. Pt was thermally evaporated utilizing the JCNS molecular beam epitaxy system which is also open to users in the framework of neutron experiments performed at the MLZ (www.mlz-garching.de).
