Single crystal and polycrystal oxoruthenates having the generalized compositions (Ba,Sr)FeCoRuO(1&#x2266;(x+y)&#x2266;5; 0&#x2266;z&#x2266;1) and (Ba,Sr)MRuO(M=Fe,Co) belong to a novel class of ferromagnetic semiconductors with applications in spin-based field effect transistors, spin-based light emitting diodes, and magnetic random access memories.

Class of ferromagnetic semiconductors

A wet-chemical method for producing strip-shaped high-temperature superconductors with a substrate, optionally with a buffer layer and with a high-temperature superconductive layer is improved by increasing the texturing and the layer thickness of the high-temperature superconductive layer. To this end, precursor solutions are applied in layers to the substrate, of which the first is low in fluorine or does not contain fluorine, and the following have a fluorine concentration that increases with each layer.

Process for the production of highly-textured, band-shaped, high-temperature superconductors

The formation of band-shaped HTSL on a metal substrate is disclosed. The HTSL includes at least one buffer layer comprising zirconates and/or rare-earth oxides. The HTSL layer is formed on the buffer layer. The buffer layer has a texturing that in the case of a RHEED measurement results in discrete reflexes and not only in diffraction rings. In particular, the buffer layer may be textured along its interface with the HTSL layer.
