Figure 18
Momentum- and time-resolved RSXD scans along [111] across the (1/2, 1/2, 1/2) magnetic superstructure reflection. The time-resolved scans show the magnetic Bragg reflection before the arrival of the laser pulse (blue) and 500 fs (a), 1 ps (b) and 10 ps (c) after (dashed red). The solid red curves are the dashed ones scaled to the same amplitude as the un-pumped (blue) peak. |
