Figure 9
(a) Gd-M₅ Auger resonance excited at 1186 eV measured in remanence with two opposite magnetization directions in Co_0.65Gd_0.35 as observed before (a) and after (b) the laser excitation. (c) Time-dependent XMCD signal measured at the Gd-M₅ Auger resonance (black dots). The laser excitation is produced by the 50 fs laser at 800 nm. The red dashed line reproduces the demagnetization dynamics simulated by combining an exponential decay function and an exponential recovery function with time constants of 35 ps and 850 ps, respectively.
