Abstract :
In this context, antidot structures in which the holes are filled with another ferromagnetic material emerged of interest in magnonic applications for unique static and dynamic properties. In this context, the static behaviors of magnetic hysteresis and magnetotransport response have been investigated in Ni80Fe20 antidot filled with Co nanostructures . A modification in the magnetic behavior and magnetotransport properties is observed in bi-component sample with respect to the constituting systems and can be ascribed the coupling between the two ferromagnetic materials . To synthesize such a bi-component material, a continuous Co layer having thickness ranging in the interval 20-40 nm has been deposited by sputtering on a Si/SiO2 substrate.
