| Popis: | Spin Hall oscillators are a promising basis for engineering spin-wave devices. The authors use a micromagnet's inhomogeneous dipolar field to confine localized spin-wave modes (magnons), and to control their response to spin currents. This offers continuously variable spatial mode dimensions and systematic tunability of the magnon spectrum, for the study of spin-orbit-torque oscillators and the development of electrically actuated spintronic circuitry. |
