Propagation of laser-generated GHz surface acoustic wavepackets in FeRh/MgO(001) below and above the antiferromagnetic-ferromagnetic phase transition
Ia. A. Mogunov, A. Yu. Klokov, N. Yu. Frolov +6
The paper experimentally investigates laser‑generated gigahertz surface acoustic wave packets propagating in FeRh thin films on MgO, focusing on how the antiferromagnetic‑to‑ferrom…
Switching picosecond magnetoacoustic regimes in a ferromagnetic waveguide
P. I. Gerevenkov, Ia. A. Mogunov, Ia. A. Filatov +4
The paper experimentally observes three interaction regimes—magneto‑elastic coupling, Cherenkov‑like radiation, and non‑resonant forcing—between laser‑generated acoustic pulses and…
Role of magnon-magnon interaction in optical excitation of coherent two-magnon modes
E. A. Arkhipova, A. E. Fedianin, I. A. Eliseyev +4
Two-magnon modes are terahertz-frequency magnetic excitations in antiferromagnets, governed by exchange interactions, involving magnons from the entire Brillouin zone and dominated…
Role of spatiotemporal nonuniformities in laser-induced magnetization precession damping
P. I. Gerevenkov, Ia. A. Filatov, L. A. Shelukhin +2
Laser-induced magnetization precession measurements in ferromagnets often reveal an anomalous decrease in the damping time near a field-induced second-order spin-orientation transi…
Switching of an antiferromagnet controlled by spin canting in a laser-induced hidden phase
A. V. Kuzikova, N. A. Liubachko, S. N. Barilo +3
During laser-induced phase transitions, fast transformations of electronic, atomic, and spin configurations often involve emergence of hidden and metastable phases. Being inaccessi…
Enhanced laser-induced single-cycle terahertz generation in a spintronic emitter with a gradient interface
L. A. Shelukhin, A. V. Kuzikova, A. V. Telegin +6
The development of spintronic emitters of broadband THz pulses relies on designing heterostructures where processes of laser-driven spin current generation and subsequent spin-to-c…
