Fig. 5: Oersted field across the wire generated by the current pulse.
From: Diameter-independent skyrmion Hall angle observed in chiral magnetic multilayers
a Oersted field, µ0HOe,z calculated for a current in a rectangular wire with a current density of 5.6 × 1011 Am−2, at a level 1 nm above the wire centre. b Average skyrmion diameter distributed across 50 nm segments (as illustrated in Fig. 5a inset) with respect to the applied field (Lines show the best linear fit). Error bars reflect the image resolution. c Slope versus field of a line fitted to the data shown in b. The line plotted is a guide to the eye. A negative slope reflects skyrmions shrinking in diameter as they traverse the wire from left to right. This is a consequence of the Oersted field generated by the current flowing through the wire. Error bars extracted from fit.
