XAS and XMCD in Co (0.4 nm)/Cu (0.4 nm)/Pt (2 nm) structures for (a) Co, (b) Cu, and (c) Pt L-edges. XAS were taken at the NI setup. XMCD were taken at both NI and GI setups for Co and Cu L-edges, and at the NI setup for Pt. μ+ and μ− denote the absorption depending on the magnetic field directions. Insets show the expanded view of L3-edge XMCD signals.
