Abstract

In order to improve the precision of domain wall (DW) dynamics measurements, we develop a coplanar waveguide-based setup, where the DW motion should be triggered by pulses of magnetic field. The latter are produced by the Oersted field of the waveguide as a current pulse travels toward its termination, where it is dissipated. Our objective is to eliminate a source of bias in DW speed estimation while optimizing the field amplitude. Here, we present the implementations of this concept for magnetic force microscopy and synchrotron-based investigation.
