Уважаемые коллеги!

На заседании Ученого совета ИТФ в пятницу 13.12 в 11:30 будет заслушан 1 доклад:
1). Александр Садовников (СГУ, Саратов)
Interconnection in magnonic networks: functional building blocks for an alternative controllable way of spin-wave and quantum computation

The content of the talk is devoted to the possible integration of magnonic devices and interconnection between them with the use of magnonics, straintronics, spin-orbitronics. In recent years much research has been directed towards the use of spin waves for signal processing at microwave and subterahertz frequencies due to the possibility to carry the information signal without the transmission of a charge current. Recent theoretical and experimental studies suggest that strain can be used to engineer energy-efficient complicated 2D and 3D material and heterostructures. The main topic of the talk will be focused on the application of the magnonic unit for signal processing and interconnection routes in the magnonic networks.  The part of the talk will be devoted to the the experimental observations of the strain-mediated spin-wave coupling phenomena in different magnonic structures based on the asymmetric adjacent magnonic crystals, adjacent magnetic yttrium iron garnet stripes and array of magnetic stripes, which demonstrates the collective spin-wave phenomena such as the discrete soliton formation.  The voltage-controlled spin-wave transport along bilateral magnonic stripes was demonstrated. The model describing the spin-wave transmission response and predicting its value is proposed based on the self-consistent equations. It was shown that the strain-mediated spin-wave channels can be used to route the magnonic information signal and thus the composite magnon-straintronic structure could be used to fabricate magnonic platforms for energy-efficient signal processing. The obtained results open new perspectives for the future-generation electronics using integrated magnonic networks.
