(Color online) TR-XMCD measurement of Fe and Ni magnetization precessions at resonance, at . Solid lines are sinusoidal fits of the Fe and Ni data sets separately.
(Color online) TR-XMCD measurement of Fe magnetization precession through the resonance condition. Solid lines are sinusoidal fits of each Fe data set separately. For clarity, the data are offset vertically.
(Color online) (a) In-plane FMR spectra of measured in situ at . (b) Phase and precessional cone angle of Fe magnetization motion across the resonance. Solid lines are the corresponding theoretical simulations from Eqs. (4) and (5).
(Color online) TR-XMCD measurements for Fe, Ni, and Co in the magnetic trilayer. The open symbols are the measured points and the solid black lines are sinusoidal fits to the data. The top panel shows the response of the different layers near the main resonance at while the bottom panel presents the data for the low bias field condition. Note the large change in phase for the Fe oscillations (, Fe) and the much smaller phase shift for the Co oscillations (, Co). For clarity, the Fe and Ni data have been offset vertically.
(Color online) Measured values for the precession cone angle (left panel) and phase of oscillation (right panel) for the Fe (triangles) and Co (circles) moments in the trilayer. The dashed lines are calculated values for the amplitude and phase assuming no coupling between the layers. Solid lines are model calculations that assume weak coupling between the two FM layers.
(Color online) Phase lags measured for a low damping/high damping magnetic bilayer, , acquired at different excitation frequencies. (a) Low frequency : both layers precess in phase; (b) high frequency: the Tb doping exerts a drag on the ) precessional motion and the precession lags behind the Co oscillations by . Solid lines are sinusoidal fits to the data.
(Color online) TR-XMCD measurements acquired at resonance, using an excitation frequency of , for a single layer. The top layer presents the average of 41 delay scans acquired at the edge while the bottom presents the oscillatory signal from a single delay scan of the edge. The oscillations are primarily out of phase for the elemental moments. Solid lines are sinusoidal fits to the data.
