  We report on a strong perpendicular magnetic anisotropy in [CoFe 0.4nm/Pd t]6
(t = 1.0-2.0 nm) multilayers fabricated by DC sputtering in a ultrahigh vacuum
chamber. Saturation magnetization, $M_s$, and uniaxial anisotropy, $K_u$, of
the multilayers decrease with increasing the spacing thickness, with a $M_s$ of
155 emu/cc and a $K_u$ of 1.14$\times 10^5$ J/m$^3$ at a spacing thickness of t
= 2 nm. X-ray absorption spectroscopy and X-ray magnetic circular dichroism
measurements reveal that spin and orbital magnetic moments of Co and Fe in CoFe
film decrease as function of Pd thickness, indicating the major contribution of
surface/interfacial magnetism to the magnetic properties of the film.
