N2 - Magnetic circular dichroism (MCD) and X-ray absorption spectra (XAS) at the Co L2,3-edge of [Co/Pd]20 and [CoB/Pd]20 multilayered films, which were fabricated at 260 °C with different magnetic layer thicknesses (δ), have been measured. The lineshapes of XAS-MCD show that the electronic state of Co 3d of the films hardly changes even when sputtered at higher temperatures. The expectation values of orbital and spin angular momentum (〈Lz〉 and 〈Sz〉) are estimated using the sum rule, and it is found that 〈Lz〉/〈Sz〉 in δ<0.5 nm is larger than that in δ>0.5 nm.
