FIG. 1.

Schematic of time-resolved measurements of spin wave packet. A spin wave packet is excitated and detected with a pair of ACPS with a gap distance . (b) Optical micrograph of ACPSs comprising a signal line and a ground line with a separation length .

FIG. 2.

(a) Spin wave signals with different gap distances, exhibiting a propagation of spin wave packet. Inset represents the delay and decay of spin wave packets. (b) Spin wave resonance frequency vs. external magnetic field for four excitation configurations. The data points are obtained by FFT analysis of time domain waveforms.

Image of FIG. 3.
FIG. 3.

Time-resolved waveforms of propagating spin wave having (a) right moving wavevector and (b) left moving wavevector . (c) Waveforms excited by an inversed excitation field . The broken lines correspond to the waveforms excited by , showing phase shifts in . (d) Nonreciprocal parameter as a function of gap distance.
