ABSTRACT:
A magnetic lamination including at least a first magnetic film, a second magnetic film and, a third magnetic film, a first intervening intermediate film intervening between the first and second magnetic films, and a second intervening intermediate film intervening between the second and third magnetic films, wherein the respective magnetic films each comprise a magnetically soft film, the first and second intervening films differ in thickness, and one of the first and second intervening films can have a zero thickness and further, the intervening intermediate film can include a transition metal and a substance which is likely to form a heterogeneous mixture with the transition metal.
