报告摘要：

Magneto-optical interaction in magnetically ordered materials allows photons to be controlled by a magnetic field, as well as to excite magnon oscillations using light. In this case, the surface of the magnetic material plays an important role: the magnitude and nature of the magneto-optical effects can be significantly modified due to boundary conditions and excitation of polariton modes.

报告人简介：

Professor Vladimir I. Belotelov, a member of the Russian Academy of Sciences, works at the Physics Department of Lomonosov Moscow State University (MSU) and leads the experimental research group at the Russian Quantum Center. After defending his PhD in 2004, he went on to defend his doctoral dissertation in 2013 at MSU. Between 2013 and 2016, he was based in Germany as part of the Humboldt Foundation program, and from 2019 until 2023 he led a Megagrant project at the Vernadsky Crimean Federal University in Simferopol, funded by the Ministry of Science and Higher Education of Russia.

His research has been published in more than 180 peer-reviewed articles (H-index is 40 on WoKn and 43 on G.Scholar).

Professor Belotelov's research focuses on magnetophotonics, ultrafast magnetism, optomagnonics, and quantum magnonics. He has authored works on enhancing the magneto-optical effect using metal nanostructures, marking the beginning of a new branch of nanophotonics: magnetoplasmonics. The group of Prof. Belotelov recently demonstrated fully optical switching based on plasmon resonance in a multilayer structure consisting of a metallic ferrimagnet and dielectric. Additionally, V.I. Belotelov has demonstrated for the first time the excitation of surface magnetostatic and exchange spin waves using femtosecond laser pulses. Currently, he is investigating inverse magneto-optical effects in magnetic nanostructures, spin dynamics in ferrimagnets near magnetic moment compensation points and ferromagnetic-superconducting hybrid qubit systems.
