The electronic and spin state of the perpendicular magnetization film TbFe
Co
was investigated by means of magnetic circular dichroism spectroscopy for each element. The samples are Tb
Fe
Co
while the ratio of a rare-earth metal Tb to transition metals Fe and Co is constant, the composition ratio of Fe and Co is changed. Changing the ratio, we estimated the expected orbital moments
of Tb 4f electrons. The macroscopic magnetic property is studied from the microscopic point of view.
