Round robin comparison on quantitative nanometer scale magnetic field measurements by magnetic force microscopy

Xiukun Hu
As a standard tool for nano-scale investigation of magnetic domain structures, magnetic force microscopy (MFM) measures the local stray magnetic field landscape of the measured sample, however, generally providing only qualitative data. To quantify the stray magnetic fields, the MFM system could be calibrated by a so-called transfer function (TF) approach which fully considers the finite extent of the MFM tip. However, albeit being comprehensive, the TF approach is not yet well established, mainly due...

Dataset for Combining Harmonic Laser Beams by Fiber Components for Refractivity–Compensating Two-Color Interferometry

Xiukun Hu, Anni Röse, Günther Prellinger, Paul Köchert, Jigui Zhu & Florian Pollinger
A perfect spatial overlap with multiple beams of different wavelengths is a prerequisite for multi–wavelength interferometry. Beam combination with the help of fibers seems to be an interesting method for this. We investigated three different types of fiber components, multi–mode wavelength division multiplexers (MM–WDMs), single–mode wavelength division multiplexers (SM–WDMs), and endlessly single–mode polarization maintaining photonic crystal fibers (PM–PCFs). All three seem potential candidates for a perfect spatial overlap of laser beams separated by an octave,...

Steffen Ketelhut & Ludwig Büermann
Set of experimental unfiltered x-ray spectra in the range of mammography qualities. The spectra can be computationally filtered to generate a wide range of x-ray spectra in this energy range.

Modulation-based long-range interferometry as basis for an optical two-color temperature sensor [Dataset]

Anni Röse, Yang Liu, Paul Köchert, Günther Prellinger, Eberhard Manske & Florian Pollinger
Investigations of an 2f/3f detection scheme for phase detection. The laser frequency of the light source is sinusoidally modulated, and the interferometric phase derived from the harmonic signals. In this article we discuss measurement scheme, approach-included challenges and present first verification experiments over a range of 20m.

Long Slender Piezo-Resistive Silicon Microprobes for Fast Measurements of Roughness and Mechanical Properties inside Micro-Holes with Diameters below 100 µm

Uwe Brand, Min Xu, Lutz Doering, Jannick Langfahl-Klabes, Heinrich Behle, Sebastian Büteﬁsch, Thomas Ahbe, Bodo Mickan, Erwin Peiner, Stefan Völlmeke, Thomas Frank, Ilia Kiselev, Michael Drexel & Michael Hauptmannl
During the past decade, piezo-resistive cantilever type silicon microprobes for high-speed roughness measurements inside high-aspect-ratio microstructures, like injection nozzles or critical gas nozzles have been developed. This article summarizes their metrological properties for fast roughness and shape measurements including noise, damping, tip form, tip wear, and probing forces and presents the ﬁrst results on the measurement of mechanical surface parameters. Due to the small mass of the cantilever microprobes, roughness measurements at very high traverse...
