Nonequilibrium Magnons and Energy Transformations in Nano-Magnetic Systems

Abstract: I shall discuss non-equilibrium magnetic excitations (magnons) in magneto-ordered systems (particles and films). A universal language of bose-gas in a nonlinear system will be used to help finding possible analogies in other nonlinear systems. Two mechanisms of microwave energy transformation of the noisy pumping to the coherent magnetic signal at room temperature will be discussed. One is the Bose-Einstein condensation of quasi-equilibrium magnons (the phenomenon was experimentally observed about 7 years ago), and another is the nonlinear noise squeezing by the microwave resonator (the phenomenon was discovered about 20 years ago). We shall also briefly consider a possibility and advantages of developing parallel processing of digital operations using the long-lived excitations in nano-systems.
