摘要：

We demonstrate functionality of magnetic logic based on a reconfigurable magnonic crystal in the form of a meander-type ferromagnetic nanowire. A ferromagnetic resonance method employing a microscopic coplanar waveguide has been used to detect the logic state of the structure coded in its magnetic ground state. Ferromagnetic resonance responses of anti-ferromagnetic and multi-cluster (mix of anti-ferromagnetic and ferromagnetic) ground states can be switched by applying a DC current in the signal line of the coplanar waveguide. Experimental demonstrations of device functionality as XOR and NOT logic gates are supported by the magnetic force microscopy images and micromagnetic simulations.
