Since its development in 1986, the Atomic force microscope (AFM) has become a revolutionary tool for surface analysis. AFM is of special interest to biologists because of its ability to operate in liquids. Applications include imaging molecules, cells, tis ...
High resolution magnetic force microscopy plays an important role in the development of magnetic data storage media. Particularly the envisioned increase of the storage density to 1TBit per sqinch within the next five years requires an ongoing development ...
In this thesis, the magnetic and structural properties of layered epitaxial film systems and clusters are presented. A main achievement is the investigation of the direct correlation between magnetism and structural or morphological details of ultrathin fi ...
NOVELTY - The microscope has a housing (12), and two actuators (14, 16) are arranged in an opposed push-pull configuration that is coupled to the housing. A support (22) is coupled to the housing and to one of the two actuators at a position that is spaced ...
Anewmicrosystem with the ability to detect magnetic microstructures based on the non-invasive Hall principle is presented. The micro-Hall plate embedded in the microsystem and scaled down to the physical limits of the employedCMOStechnology has an active a ...
Periodic arrays of elongated cobalt islands exchange coupled to continuous Permalloy thin films were fabricated using silicon nitride stencil masks and the magnetic spin configurations during magnetization reversal were studied with photoemission electron ...
This thesis reports on the design and construction of a novel experimental setup for the study of surface magnetic systems. This setup consists of a scanning tunneling microscope (STM) designed for ultra high vacuum (UHV) operating at T ≲ 1 K and str ...
We employ variable-temperature spin-polarized scanning tunneling microscopy in constant current mode to read the magnetic state of monodomain cobalt nanoparticles on Pt(111). In order to avoid stray fields we use in situ prepared antiferromagnetically (Cr) ...
The transition metal tellurium oxychloride, Ni-5(TeO3)(4)Cl-2, has been investigated by high-field electron-spin resonance for frequencies up to 3 THz, at temperatures well below the magnetic ordering at 23 K. At zero external field several resonance modes ...
Many applications in materials science, life science and process control would benefit from atomic force microscopes (AFM) with higher scan speeds. To achieve this, the performance of many of the AFM components has to be increased. In this work, we focus o ...
