ABSTRACT
This chapter discusses the interpretation of the effect in terms of adiabatic spin transfer torque and its measurement using both inductive and magneto-optical techniques. It reviews the work done on current-induced modification of spin wave dynamics. The chapter also discusses the general idea of a Doppler effect for spin waves and derives the expression of the frequency shift from the standard equations of the spin transfer torque (STT). It describes the other effects that accompany the current- induced spin wave Doppler shift (CISWDS), namely the frequency shifts induced by magnetic asymmetries and by the Oersted field generated by the current and the current-induced modification of spin wave relaxation, which allows one to evaluate the nonadiabatic correction to the STT. The chapter describes explicitly the derivation of the effect from the basic equation of motion of the magnetization, including the STT.
