Optical creation and annihilation of skyrmion patches in a bulk chiral magnet
Jantje Kalin, Sibylle Sievers, Daniel Kalin +6
A key challenge for the realization of future skyrmion devices comprises the controlled creation, annihilation and detection of these topologically non-trivial magnetic spin textur…
Optically excited spin dynamics of thermally metastable skyrmions in FeCoSi
Jantje Kalin, Sibylle Sievers, Heiko Füser +5
We investigate the microwave spin excitations of the cubic chiral magnet FeCoSi as driven by the thermal modulation of magnetic interactions via laser heating and…
A Ti/Pt/Co multilayer stack for transfer function based magnetic force microscopy calibrations
Baha Sakar, Sibylle Sievers, Alexander Fernandez Scarioni +4
Magnetic force microscopy is a widespread technique for imaging magnetic structures with a resolution of some 10 nanometers. MFM can be calibrated to obtain quantitative spatially…
Quantum calibrated magnetic force microscopy
Baha Sakar, Yan Liu, Sibylle Sievers +7
We report the quantum calibration of a magnetic force microscope (MFM) by measuring the two-dimensional magnetic stray field distribution of the MFM tip using a single nitrogen vac…
Thermoelectric signature of individual skyrmions
Alexander Fernández Scarioni, Craig Barton, Héctor Corte-León +8
We experimentally study the thermoelectrical signature of individual skyrmions in chiral Pt/Co/Ru multilayers. Using a combination of controlled nucleation, single skyrmion annihil…
Uncertainty Analysis of Stray Field Measurements by Quantitative Magnetic Force Microscopy
Xiukun Hu, Gaoliang Dai, Sibylle Sievers +4
Magnetic force microscopy (MFM) measurements generally provide phase images which represent the signature of domain structures on the surface of nanomaterials. To quantitatively de…
Traceably Calibrated Scanning Hall Probe Microscopy at Room Temperature
Manuela Gerken, Aurélie Solignac, Davood Momeni Pakdehi +5
Fabrication, characterization and comparison of gold and graphene micro- and nano-size Hall sensors for room temperature scanning magnetic field microscopy applications is presente…
Investigation of a possible electronic phase separation in the magnetic semiconductors GaMnAs and GaMnP by means of fluctuation spectroscopy
Martin Lonsky, Jan Teschabai-Oglu, Klaus Pierz +6
We present systematic temperature-dependent resistance noise measurements on a series of ferromagnetic GaMnAs epitaxial thin films covering a large parameter space in…
Domain wall magneto-Seebeck effect
Patryk Krzysteczko, Xiukun Hu, Niklas Liebing +2
The interplay between charge, spin, and heat currents in magnetic nano systems subjected to a temperature gradient has lead to a variety of novel effects and promising applications…
Towards wafer scale inductive characterization of spin transfer torque critical current density of magnetic tunnel junction stacks
Sibylle Sievers, Niklas Liebing, Santiago Serrano-Guisan +12
We explore the prospects of wafer scale inductive probing of the critical current density for spin transfer torque switching of a CoFeB/MgO/CoFeB magnetic tunnel junction…
Broadband ferromagnetic resonance characterization of GaMnAs thin films
Aymen Ben Hamida, Sibylle Sievers, Klaus Pierz +1
The precessional magnetization dynamics of GaMnAs thin films are characterized by broadband network analyzer ferromagnetic resonance (FMR) in a coplanar geometry at cryogenic tempe…
Quantitative measurement of the magnetic moment of an individual magnetic nanoparticle by magnetic force microscopy
Kai-Felix Braun, Sibylle Sievers, Dietmar Eberbeck +4
We demonstrate the quantitative measurement of the magnetization of individual magnetic nanoparticles (MNP) using a magnetic force microscope (MFM). The quantitative measurement is…
