Abstract

Propagation of spin waves was studied in electrical ways. Spin waves were excited locally in a permalloy strip by a microwave through a coplanar waveguide and were detected by an electrical technique based on spin rectification effect. By a local magnetic field induced by a DC current, the propagation of spin waves was suppressed in the permalloy strip. We demonstrated that spin wave excitation, manipulation and detection in permalloy strip are possible by electrical ways. And microwave leakage from the coplanar waveguide and local excitation of spin waves are discussed in this paper.
