Figure 5
Top: XANES and XMCD signals for GdCo₂ at the Gd L₃-edge and Co K-edge. Measurement time for each data set was 40 min. Lock-in frequency was 13 Hz, and the time constant in the lock-in amplifier 100 ms. Bottom: XMCD amplitude as a function of magnetic field for GdCo₂, with fixed energy at the XMCD peak of the Gd L₃-edge.
