Fast scanning nitrogen-vacancy magnetometry by spectrum demodulation
P. Welter, B. A. Josteinsson, S. Josephy +4
We demonstrate a spectrum demodulation technique for greatly speeding up the data acquisition rate in scanning nitrogen-vacancy center magnetometry. Our method relies on a periodic…
Scanning nitrogen-vacancy center magnetometry in large in-plane magnetic fields
P. Welter, J. Rhensius, A. Morales +5
Scanning magnetometry with nitrogen-vacancy (NV) centers in diamond has emerged as a powerful microscopy for studying weak stray field patterns with nanometer resolution. Due to th…
Parallel time integration using Batched BLAS (Basic Linear Algebra Subprograms) routines
Konstantin Herb, Pol Welter
We present an approach for integrating the time evolution of quantum systems. We leverage the computation power of graphics processing units (GPUs) to perform the integration of al…
Co-existence of Bloch and Neel walls in a collinear antiferromagnet
M. S. Wornle, P. Welter, M. Giraldo +4
We resolve the domain-wall structure of the model antiferromagnet using nanoscale scanning diamond magnetometry and second-harmonic-generation microscopy. W…
Current-induced fragmentation of antiferromagnetic domains
M. S. Wörnle, P. Welter, Z. Kašpar +7
Electrical and optical pulsing allow for manipulating the order parameter and magnetoresistance of antiferromagnets, opening novel prospects for digital and analog data storage in…
High-speed domain wall racetracks in a magnetic insulator
Saül Vélez, Jakob Schaab, Martin S. Wörnle +9
Recent reports of current-induced switching of ferrimagnetic oxides coupled to a heavy metal layer have opened realistic prospects for implementing magnetic insulators into electri…
