Enhanced Spin Relaxation in Nanocrystals of Different Geometries

Abstract:

Article Preview

Various coherent magneto-dynamical effects can lead to the phenomenon qualitatively similar to optical super-radiation (SR). To realize SR for spins, a sample should be placed in a passive resonance circuit that, in response to the magnetization motion, generates a feedback magnetic field common for all the spins of the system. The electromagnetic radiation emitted by an assembly of nano-entities (molecules, dots, grains) by way of the feedback effect establishes their coherence thus greatly reducing the duration and enhancing the intensity of the deexcitation pulse.
