Influence of transverse fields on domain wall pinning in ferromagnetic nanostripes
We report an experimental study dealing with the influence of in-plane transverse fields on the domain wall pinning in ferromagnetic nanostripes. We analyzed the pinning probability and depinning fields...
PublikationenSpatial optical filter sensor based on hollow-core silica tube
A spatial optical filter based on a hollow-core silica tube is proposed. Because of the hollow-core dimensions, it is possible to obtain a periodical spatial filter ranging from 1200 to 1700 nm with a...
PublikationenNanomechanical resonators
This paper reviews a current state of the development and application of nanomechanical resonators. The basic methods of manufacturing and characterization of nanoscale mechanical resonators are described....
PublikationenQuantum superposition of magnetic flux states in a superconducting loop
Results of the recent experiments have clear and convincingly demonstrated that superconducting circuits with certain parameters can be in quantum superposition of macroscopically distinct states. This...
PublikationenMultiphoton transitions in Josephson-junction qubits
Two basic physical models, a two-level system and a harmonic oscillator are realized on the mesoscopic scale as coupled qubit and resonator. The realistic system includes moreover the electronics for controlling...
PublikationenHeat cost of parametric generation of microwave squeezed states
In parametric systems, squeezed states of radiation can be generated via extra work done by external sources. This eventually increases the entropy of the system despite the fact that squeezing is reversible.We...
PublikationenInterlayer-coupled spin vortex pairs and their response to external magnetic fields
We report on the response of multilayer spin textures to static magnetic fields. Coupled magnetic vortex pairs in trilayer elements (ferromagnetic/nonmagnetic/ferromagnetic) are imaged directly by means...
PublikationenSub-diffraction imaging on standard microscopes through Photobleaching Microscopy with non-linear Processing
Discerning organelles and molecules at nanometer resolution is revolutionizing biological sciences. However, such technology is still limitedly available for many cell biologists. We present here a novel...
PublikationenFast M2 measurement for fiber beams based on modal analysis
We report on a fast and experimentally easy technique for measuring the beam ropagation ratio M2 of light guided by optical fibers. A holographic filter enables us to determine amplitudes and phases of...
PublikationenEvaluation of Colloids and Activation Agents for Determination of Melamine Using UV-SERS
UV-SERS measurements offer a great potential for environmental or food (detection of food contaminats) analytics. Here, the UV-SERS enhancement potential of various kinds of metal colloids, such as Pd,...
