Abstract

With a thin Co layer inserted into the L1₀-FePt(3 nm)/Fe(2 nm) ECC structure, a large reduction of coercivity is observed in such a graded trilayer, with a minimum value of 1.45 kOe when the Co thickness is 2 nm, similar to that of FePt(3 nm)/Fe(4 nm). The magnetization reversal in both FePt/Fe and FePt/Co/Fe structures is carefully studied by the vector vibrating sample magnetometer. The nucleation, wall compression, and irreversible magnetization rotation are discussed.
