SPIN WAVES IN MAGNETIC MICROSTRUCTURES: MAGNON LOGIC AND INFORMATION PROCESSING

This paper presents a review of the current state of research in magnonics aimed at developing energy-efficient element base for information systems and technologies based on the effects of excitation, propagation and detection of spin waves in thin-film magnetic micro- and nanostructures. The progress achieved in the development of materials for spin waveguides, as well as in the methods of excitation, reception and control of spin wave propagation is discussed. Practical implementations of the effects of spin wave propagation in magnetic microstructures for constructing a number of logical keys, processing magnetic images, neuromorphic computing, ultra-high-frequency information processing devices and magnetic sensors, as well as problems that need to be solved for further development are considered.
