Novel concept of tunable spin waves source

Ferrolab team lead by Nikolai Khokhlov in collaboration with Russian Quantum Center suggested a novel concept of a tunable source of magnetostatic spin waves. They've come up with the idea of exciting a thin magnetic film by a femtosecond laser pulse near a domain wall. Micromagnetic modelling have shown that laser spot and domain wall form a kind of a resonator for the generated waves. Bacause of it, it is possible to tune the spectrum of the wave propagating out of such resonator in several ways. The paper has been recently published in Journal of Magnetism and Magnetic Materials.

2021 starts for FerroLab with a new paper

Despite being developed decades ago, Raman and infrared spectroscopies of complex compounds keep bringing new fascinating results. This time Roman Dubrovin and his colloborators from Ioffe Institute, Institute of Spectroscopy of RAS, HFML and Rabdoud University, Ural Federal University, ESRF, and Peter the Great Polytechnic University have solved lattice dynamics of the cobalt orthoborate Co3(BO3)2 - material where magnetic ions occupy different crystallographic positions, which may affect not only magnetic but also structural properties. The paper "Lattice dynamics of cobalt orthoborate Co3(BO3)2 with kotoite structure​" has just been published in Journal of Alloys and Compounds.

2020 ended with two new publications from Ferrolab

In December the paper "Photoelasticity of VO2 nanolayers in insulating and metallic phases studied by picosecond ultrasonics" by Iaroslav Mogunov and Alexandra Kalashnikova and co-authors from University of Nottingem, University of Puerto Rico and Lebedev Physical Institute of RAS was published in Physical Review Materials. In this paper we explore for the first time photoelastic properties of VO2 - phase change material with several promissing applications in electronics and photonics. 

Also in December the paper Iaroslav Filatov, Petr Gerevenkov, Alexandra Kalashnikova and Nokolai Khokhlov and collaborators from University of Nottingham published the proceeding paper "Spectrum evolution of magnetostatic waves excited through ultrafast laser-induced heating" in Journal of Physics: Conference Series. This is another step in our quest towards ultrafast opto-magnonics: ultrafast tuning of properties of magnonic media and steering spin waves.

New paper by FerroLab in Nature Communications

The paper "Large non-thermal contribution to picosecond strain pulse generation using the photo-induced phase transition in VO2" has been just published in Nature Communications! This remarkable work by Iaroslav Mogunov, Anatolii Fedianin and Alexandra Kalashnikova and colleagues from University of Nottingham and University of Puerto Rico demonstrates that a thin film of vanadium dioxide serves as a highly efficient opto-acoustic transducer for such applications as acoustic nanoscopy. Owing to ultrafast phase transition, VO2 converts a femtosecond laser pulse into a picosecond strain pulse of gaint amplitude of ~1% with exceptionally low accompanying heating.
