Magnetization dynamics of the spin wave repeater upon application of the voltage across the piezoelectric layer of the ME cell.
The falling edge of the clock (point A) denotes the detection of the spin wave signal by turning off the voltage. The phase of the spin wave dictates the direction of tilting of the magnetization. The rising edge of the clock (point B) denotes the transmission of the stored information by exciting spin waves via the application of the voltage.
