Abstract: Magnetic reversal in a (110)-oriented [DyFe2(60Å)/YFe2(240Å)]×15 [ DyF e 2 ( 60   Å ) / YF e 2 ( 240   Å ) ] × 15 multilayer film is investigated using magnetometry, micro-magnetic modeling, and element-specific soft x-ray magnetic circular dichroism. At temperatures between ∼60 and 120 K, the magnetic reversal involves a two-step process. It is shown that the reversal mechanism can be described as switching from an in-plane [001] reversed anti-ferromagnetic state, to an out-of-plane [100] transverse spring exchange state, and finally to an in-plane [001⎯⎯] [ 00 1 ¯ ] magnetic exchange spring state.
