We examined the macroscopic and element selective magnetic properties by Kerr hysteresis loop and X-ray magnetic circular dichroism (MCD) spectroscopy, respectively, of [Tb $_{20}$ Co $_{80}$ ] $_{20}$ /Pd multilayered films and Tb $_{20}$ Co $_{80}$ single layered films with several TbCo layer thicknesses. We found that the macroscopic magnetic properties of TbCo/Pd and TbCo films were dependent on the TbCo layer thickness by Kerr effect measurement. We estimated the Lz, Sz and Lz/Sz values from MCD measurements at Co L2,3 edges. The values of Lz and Sz of both types of films were the almost same each other, while the clear distinction of Kerr effects was observed.
