A fundamental issue in developing spin wave (SW) devices with ultralow power consumption is exploring energy-efficient excitation with nanoscale spatial resolution. We numerically studied the voltage-induced excitation of a geometrically confined standing spin wave (SSW), which is suitable for the downsizing of various SW devices. The micromagnetic configuration of the excited SSW, the resonance spectrum, and the structural size effects were investigated. In addition, a possible application to a SSW-based logic operation was demonstrated in a nanowire with lateral dimensions of 20 nm × 100 nm.
