Abstract
We have grown high-quality magnetite micrometric islandson rutheniumstripes on sapphire through a combination of magnetron sputtering(Ru film), high-temperature molecular beam epitaxy (oxide islands),and optical lithography. The samples have been characterized by atomicforce microscopy, Raman spectroscopy, X-ray absorption and magneticcircular dichroism in a photoemission microscope. The magnetic domainson the magnetite islands can be modified by the application of currentpulses through the Ru stripes in combination with magnetic fields.The modification of the magnetic domains is explained by the Oerstedfield generated by the electrical current flowing through the stripesunderneath the magnetite nanostructures. The fabrication method isapplicable to a wide variety of rock salt and spinel oxides.
