2nd best young scientist talk at the Winter School on Semiconductor Physics

Anastasia Beresneva, 3rd year undergraduate student from our lab, received the 2nd award for her talk at the traditional competition among young scientists at Winter School on Semiconductor Physics held on February 26 - March 1 in Zelenogorsk. The talk of Anastasia was about laser-induced switching and precession in exchange-biased heterostructures. Other two students from our lab, Artem Brulev and Valeria Kovaleva also presented great talks at this competition.

Publication in Science and Technology of Advanced Materials (STAM) on improved spintronic emitter of THz pulses

We are opening a new direction of research in our lab by publishing our first results on generation of THZ pulses in a spintronic emitter. The emitter is a multilayer structure of Pt/Co. When Co is excited by a femtosecond laser pulses, a short pulse of a spin current flows into Pt, and is converted therein into a short pulse of a charge current. This leads to emission of a so-called single-cycle THz pulse. Nowadays, a lot of efforts is dedicated to improving efficiency of such emitters. Leonid Shelukhin, Anna Kuzikova, Alexandra Kalashnikova together with colleagues from Far East Federal University, Institute of Metal Physics, and Korea University have shown that efficiency can be increased by a factor of two by design of the nanometer-thick interfacial layer between Co and Pt. The paper "Enhanced laser-induced single-cycle terahertz generation in a spintronic emitter with a gradient interface" is now published in STAM journal.

Journal of Applied Physics Editor's pick

A paper "Tunable quasi-discrete spectrum of spin waves excited by periodic laser patterns" by Iaroslav Filatov, Petr Gerevenkov, Nikolay Khokhlov and Alexandra Kalashnikova was just published in Journal of Applied Physics. It is displayed at the journal homepage as an Editor's pick! This theoretical work shows how femtosecond laser excitation forming periodic pattern in space enables generation of magnetostatic waves and tuning their spectrum by choosing different excitation mechanisms and laser pulse polarization.
