Continuous generation of spinmotive force in a patterned ferromagnetic film

Phys Rev Lett. 2011 Dec 2;107(23):236602. doi: 10.1103/PhysRevLett.107.236602. Epub 2011 Nov 30.

Abstract

We study, both experimentally and theoretically, the generation of a dc spinmotive force. By exciting a ferromagnetic resonance of a comb-shaped ferromagnetic thin film, a continuous spinmotive force is generated. Experimental results are well reproduced by theoretical calculations, offering a quantitative and microscopic understanding of this spinmotive force.
