SATURATION MAGNETIC-MOMENTS OF CO MN MULTILAYERS/

Co(1 nm)/Mn(t nm) multilayers were prepared by deposition in an ultra high vacuum of 10(-10) Torr. The multilayers consist of Mn and Co laye rs whose (110) and (0001) planes are parallel to the substrate plane, respectively. For multilayers with Mn layer thickness, t, between 1.3 and 3.5 nm, the lattice spacings of Mn layers dilated in the direction normal to their layer plane and ferromagnetism of Mn layers is presum ed at specific thickness of Mn layers. This anomalous magnetism of Mn seems to strongly depend on the deposition conditions of the Mn buffer layer.
