结果表明，在脉冲微波激励下，磁性绝缘体-非磁性金属结构中自旋波诱导的逆自旋霍尔电压的时间行为与产生它的直接激发的自旋波模式的时间演化明显不同。这种不同的时间行为归因于绝缘体-金属界面上长寿命二次自旋波模的激发。
It is demonstrated that upon pulsed microwave excitation, the temporal behavior of a spin-wave induced inverse spin Hall voltage in a magnetic insulator-nonmagnetic metal structure is distinctly different from the temporal evolution of the directly excited spin-wave mode from which it originates. The difference in temporal behavior is attributed to the excitation of long-lived secondary spin-wave modes localized at the insulator-metal interface.
