Ultrafast optical excitation of coherent magnons in antiferromagnetic NiO
Christian Tzschaschel, Kensuke Otani, Ryugo Iida +5
In experiment and theory, we resolve the mechanism of ultrafast optical magnon excitation in antiferromagnetic NiO. We employ time-resolved optical two-color pump-probe measurement…
Spectral dependence of photoinduced spin precession in DyFeO3
Ryugo Iida, Takuya Satoh, Tsutomu Shimura +4
Spin precession was nonthermally induced by an ultrashort laser pulse in orthoferrite DyFeO3 with a pump-probe technique. Both circularly and linearly polarized pulses led to spin…
Spin Oscillations in Antiferromagnetic NiO Triggered by Circularly Polarized Light
Takuya Satoh, Sung-Jin Cho, Ryugo Iida +7
Coherent spin oscillations were non-thermally induced by circularly polarized pulses in fully compensated antiferromagnetic NiO. This effect is attributed to an entirely new mechan…
