Spin-current-mediated rapid magnon localisation and coalescence after ultrafast optical pumping of ferrimagnetic alloys

E. Iacocca, T-M. Liu, A. H. Reid +31

Sub-picosecond magnetisation manipulation via femtosecond optical pumping has attracted wide attention ever since its original discovery in 1996. However, the spatial evolution of…

Vanishing skyrmion Hall effect at the angular momentum compensation temperature of a ferrimagnet

Yuushou Hirata, Duck-Ho Kim, Se Kwon Kim +14

Charged particles exhibit the Hall effect in the presence of magnetic fields. Analogously, ferromagnetic skyrmions with non-zero topological charges and finite fictitious magnetic…

Laser-induced antiferromagnetic-like resonance in amorphous ferrimagnets

S. Mizukami, Y. Sasaki, D. -K. Lee +4

The magnetization dynamics for ferrimagnets at the angular momentum compensation temperature T_A is believed to be analogous to that for antiferromagnets. We investigated the pulse…

Low magnetic damping of ferrimagnetic GdFeCo alloys

Duck-Ho Kim, Takaya Okuno, Se Kwon Kim +12

We investigate the Gilbert damping parameter for rare earth (RE)-transition metal (TM) ferrimagnets over a wide temperature range. Extracted from the field-driven magnetic domain-w…

Correlation between Magnetic Properties and Depinning Field in Field-Driven Domain Wall Dynamics in GdFeCo Ferrimagnets

Tomoe Nishimura, Duck-Ho Kim, Yuushou Hirata +7

The influence of temperature on the magnetic-field-driven domain wall (DW) motion is investigated in GdFeCo ferrimagnets with perpendicular magnetic anisotropy (PMA). We find that…
