Gefügebildung und Verdichtungsvorgänge bei weichmagnetischen Ferriten
(2006-07-13)Microstructural tailoring is used to modify the electromagnetic properties of softmagnetic MnZn and NiZn ferrites, which are broadly used in all types of electronics.High permeability MnZn ... -
Herstellung und Charakterisierung metallorganisch deponierter Pufferschichten für YBa2Cu3O7
(2004-01-09)In this work the growth of buffer layers for the high temperature superconductor YBa2Cu3O7 by metal-organic-deposition (MOD) is investigated. Texture formation in CeO2-, Gd-doped CeO2 (CGO)- ... -
Ionenstrahlunterstütztes Wachstum von Zinn-dotierten Indiumoxid-Filmen
(2004-05-24)In this work the optical, electrical and microstructural properties of tin-doped indium oxide (ITO) thin films deposited by ion beam assisted deposition (IBAD) were investigated. One aim ... -
Mechnismen der Stromunterdrückung in supraleitenden YBa2Cu3O7-d Kleinwinkelkorngrenzen
(2004-05-10)In highly textured thin films of the high-temperature superconductor YBa2Cu3O7-d (Y-123) intragranular critical current densities of some 1011 A/m2 at 4.2 Kelvin can be achieved. In contrast to this, in bicrystalline samples ... -
Mikrostruktur und Wachstum bei der ionenstrahlunterstützten Deposition von Yttrium-stabilisierten Zirkonoxid-Filmen
(2003-02-26)In this work biaxially aligned yttria-stabilized zirconia (YSZ) films fabricated by ion-beam-assisted deposition (IBAD) at room temperature were studied by transmission electron microscopy ... -
Oxidation und epitaktische Oxidation von Nickel und Nickellegierung
(2002-11-08)Strongly textured superconducting YBaCuO tapes can be prepared by an epitaxial deposition on thermo-mechanically textured metal tapes (RABiTS) covered with an oxide buffer layer as a diffusion ... -
Selbstorganisation magnetischer Nanopartikel auf facettierten Saphir-Substraten
(2005-06-14)Self-organisation has been used in this work in many various ways. On the one hand a self-assembling process lead to a transformation of the plane surface of the m-plane Al2O3-substrate ...
