Titel:
Reprogrammable magnonic crystals formed by interacting ferromagnetic nanowires 
Abstract:
Spin-wave (SW) modes are addressed which are confined in thin individual [Ni.sub.80][Fe.sub.20] nanowires with widths ranging from 220 to 360 nm. In periodic arrays with an edge-to-edge separation of down to 100 nm, confined modes of neighboring nanowires are found to couple coherently and form allowed minibands and forbidden frequency gaps. This gives rise to a one-dimensional magnonic crystal. We present all-electrical SW spectroscopy data and micromagnetic simulations. We find that the...    »
