Magnetization dynamics in nanomagnets has attracted broad interest since itwas predicted that a dc-current flowing through a thin magnetic layer cancreate spin-wave excitations. These excitations are due to spin-momentumtransfer, a transfer of spin angular momentum between conduction electrons andthe background magnetization, that enables new types of information processing.Here we show how arrays of spin-torque nano-oscillators (STNO) can createpropagating spin-wave interference patterns of use for memory and computation.Memristic transponders distributed on the thin film respond to threshold tunnelmagnetoresistance (TMR) values thereby detecting the spin-waves and creatingnew excitation patterns. We show how groups of transponders create resonant(reverberating) spin-wave interference patterns that may be used forpolychronous wave computation of arithmetic and boolean functions andinformation storage.
