Ni80Fe20/Ni binary nanomagnets for logic applications

We demonstrate the functionality of Ni80Fe20/Ni binary nanostructures cells fabricated using self-aligned shadow deposition technique in logic applications. Depending on the magnetic ordering of the cells, distinct dynamic states probed by broadband ferromagnetic resonance spectroscopy are realized. We show that the magnetic ordering can be manipulated to achieve logic operations by controlling the amplitude and the orientation of reset fields. Magnetic force microscopy and micromagnetic simulations were used to validate our experimental results.
