Abstract
The hybrid exchange spring behavior in a bilayer consisting of an epitaxial film of Fe (500 A)/Smu2^}Co7}(350 A) deposited onto a Cr(200 A) buffered MgO(110) substrate was investigated using the magneto-optical indicator film technique. Two critical magnitudes of the remagnetizing magnetic field were found that dramatically change the bilayer remnant magnetization. One of them is determined by the exchange spring penetration in the interface; another determined by the hybrid spin spiral transformation to domain walls in the hard ferromagnet layer. Unexpected dependences of the average remnant magnetization direction on the external magnetic field direction and value are revealed.Citation
