摘要：

The k-space origin of the long-period (18 Angstrom) oscillation in the interlayer magnetic coupling of Fe/Cr(100) multilayers is investigated by means of angle-resolved photoemission by probing quantum well (QW) states at the Fermi energy for epitaxial Cr grown on an Fe(100) whisker at 300 degrees C. The periodicity of the intensity oscillations of the Cr QW states in the vicinity of the d-derived ''lens'' feature of the Fermi surface is 17+/-2 Angstrom. Thus the lens is identified as a prime candidate for the origin of the long period.
