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 ... -
Elemental resolved magnetism of Gadoliniumnitride layers and GdN/Fe multilayers
(2004-12-08)Gadoliniumnitride is a semiconducting ferromagnet with a supposed spin polarisation of 100%. The ferromagnetic ordering is a complex interplay of the different electrons states in the ... -
Scanning Tunnelling Microscopy of Co-impurified Noble Metal Surfaces: Kondo-Effect, Electronic Surface States and Diffusive Atom Transport
(2004-11-12)The scanning tunnelling microscope (STM) was used to investigate the properties of nanoscale structures on (111)-oriented Ag and Cu films. The special focus is on their electronic states ... -
Untersuchungen zur Korngrenzensegregation in nanokristallinen Al-Cu- und Co-P-Legierungen mittels 3d-Atomsondentomographie
(2003-11-28)The objective of this work is the characterization of nanocrystalline Al-Cu and Co-P alloys by means of the tomographic atom probe (TAP) and other characterizing techniques. It is of ... -
Excimer laser treatments of iron, aluminum and silicon substrates in nitrogen and methane atmospheres
(2003-03-19)Materials processing by laser irradiation is an expanding field with attractive technological applications. Among all laser-based treatments, the irradiation of metals and semiconductors ... -
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 ... -
Spannungen, Dehnungen und Lage der Phasengrenzen in dünnen Nb- und Y-Schichten bei Wasserstoffbe- und -entladung
(2002-07-17)In this work the influence of the stresses induced by hydrogen loading on the position of phase boundaries in niobium and yttrium thin films is studied. The films were loaded with hydrogen ... -
Raster-Thermospannungs-Mikroskopie der Interferenz von Elektronenwellen auf der Au(111)-Oberfläche
(2002-02-18)The interference pattern of scattered electron waves is studied for the 2D-electron gas of the Au(111)-surface. For this purpose, the local thermovoltage across the tunneling junction of ... -
Hochauflösende Untersuchung der lokalen Wasserstoffverteilung in metallischen Multischichten mit Hilfe der tomographischen Atomsonde und der Sekundärionenmassenspektrometrie
(2001-11-07)Chemical analyses of hydrogen loaded metallic multilayers on a subnanometer scale using the time-of-flight-methods tomographic atomprobe (TAP) and secondary ion mass spectrometry (SIMS) are reported. The results are discussed ... -
Impurity-induced resonant Raman scattering in GaAs below the band gap at low temperature
(2001-11-07)Acceptor-induced resonance Raman scattering (RRS) below the band gap in lightly doped p-type GaAs is investigated at 2 K. The Raman scattering intensities are measured and analyzed. Both impurity-induced one-phonon Raman ... -
Raumzeitliche Dynamik optisch angeregter Elektron-Loch-Plasmen in Galliumarsenid
(2001-05-04)Applying pump and probe differential reflection and transmission of femtosecond light pulses for either co- or counterpropagating pump and probe geometries, a direct time of flight method ... -
X-ray magnetic circular dichroism in iron/rare-earth multilayers and the impact of modifications of the rare earth's electronic structure
(2001-02-22)This work illuminates the possibilities of circular magnetic dichroism in X-ray absorption (XMCD) for the studies of ordered magnetism. The element and electron-shell sensitivity of this ... -
Structure and function of K<SUB>ATP</SUB>-channels in inspiratory neurons of mice
(2000-12-13)The respiratory center within the brainstem is one of the most active neuronal networks in the brain that generates rhythmic activity for lifetime. Such extreme stability requires efficient ...
