Disentangling lattice and electronic instabilities in the excitonic insulator candidate TaNiSe by nonequilibrium spectroscopy
Kota Katsumi, Alexandr Alekhin, Sofia-Michaela Souliou +7
TaNiSe is an excitonic insulator candidate showing the semiconductor/semimetal-to-insulator (SI) transition below = 326 K. However, since a structural transi…
Nondestructive femtosecond laser lithography of Ni nanocavities by controlled thermo-mechanical spallation at the nanoscale
V. V. Temnov, A. Alekhin, A. Samokhvalov +3
We present a new approach to femtosecond direct laser writing lithography to pattern nanocavities in ferromagnetic thin films. To demonstrate the concept we irradiated 300~nm thin…
Generation of exchange magnons in thin ferromagnetic films by ultrashort acoustic pulses
V. Besse, A. V. Golov, V. S. Vlasov +5
We investigate generation of exchange magnons by ultrashort, picosecond acoustic pulses propagating through ferromagnetic thin films. Using the Landau-Lifshitz-Gilbert equations we…
Observation of the nonlinear Wood's anomaly on periodic arrays of nickel nanodimers
Ngoc-Minh Tran, Ioan-Augustin Chioar, Aaron Stein +6
Linear and nonlinear magneto-photonic properties of periodic arrays of nickel nanodimers are governed by the interplay of the (local) optical response of individual nanoparticles a…
Magneto-optical properties of Au upon the injection of hot spin-polarized electrons across Fe/Au(001) interfaces
A. Alekhin, I. Razdolski, M. Berritta +7
We demonstrate a novel method for the excitation of sizable magneto-optical effects in Au by means of the laser-induced injection of hot spin-polarized electrons in Au/Fe/MgO(001)…
Femtosecond spin current pulses generated by the non-thermal spin-dependent Seebeck effect and interacting with ferromagnets in spin valves
Alexandr Alekhin, Ilya Razdolski, Nikita Ilin +8
Using the sensitivity of magneto-induced second harmonic generation to spin currents (SC), we demonstrate in Fe/Au/Fe/MgO(001) pseudo spin valves the generation of 250 fs-long SC p…
Nanoscale confinement of ultrafast spin transfer torque exciting non-uniform spin dynamics by femtosecond spin current pulses
Ilya Razdolski, Alexandr Alekhin, Nikita Ilin +5
Spintronics had a widespread impact over the past decades due to transferring information by spin rather than electric currents. Its further development requires miniaturization an…
Ultrafast electron-phonon-magnon interactions at noble metal-ferromagnet interfaces
V. Shalagatskyi, O. Kovalenko, V. Shumylo +8
Ultrafast optical excitation of gold-cobalt bilayers triggers the nontrivial interplay between the electronic, acoustic, and magnetic degrees of freedom. Laser-heated electrons gen…
