Fig. 10.9 XFMR results of exchange-coupled NiFe/CoFe bilayer. a and b XMCD signals measured
at Co and Ni L 2 edges as a function of delay time between X-ray pulse and 8 GHz RF field. a and
b show delay scans for the acoustic mode (at 37 mT) and optic mode (at 3 mT), respectively. The
Co and Ni precession are anti-phase (167◦52) in the optic mode and in-phase (7◦52) in the acoustic
mode. c XFMR precessional plots as a function of applied field showing the change in amplitude
and phase of the Ni and Co precessions. d Schematics of the bilayer grown on MgO substrate.
