Correlation of Magnetistatic Pulses using Active Delay Line

Abstract

The availability possibility of active delay line for the signal correlation of magnetostatic wave (MSW) in thin yttrium-iron garnet (YIG) films has been investigated. The principle of functioning is based on the nonlinearity interaction spin waves with each other and electromagnetic pumping. The possibility of signal compression and pulse stretching of backward volume MSW was shown. The dependence of pulse width on pumping power has been investigated.
