Control and detection of spin order in ferromagnetic materials is the main principle enabling
magnetic information to be stored and read in current technologies. Antiferromagnetic …

In the last two decades non-equilibrium spectroscopies have evolved from avant-garde
studies to crucial tools for expanding our understanding of the physics of strongly correlated …

Coherent THz optical lattice and hybridized phonon–magnon modes are triggered by
femtosecond laser pulses in the antiferromagnetic van der Waals semiconductor FePS3 …

Terahertz magnetic fields with amplitudes of up to 0.4 Tesla drive magnon resonances in
nickel oxide while the induced dynamics is recorded by femtosecond magneto-optical …

The understanding of how the sub-nanoscale exchange interaction evolves in macroscale
correlations and ordered phases of matter, such as magnetism and superconductivity …

The reciprocal interaction between spins and light has long been one of the main topics in
fundamental studies of magnetism. Recent developments of nanolitography and other …

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 …

Interfaces in heavy metal (HM)-antiferromagnetic insulator (AFI) heterostructures have
recently become highly investigated and debated systems in the effort to create spintronic …

A nearly single cycle intense terahertz (THz) pulse with peak electric and magnetic fields of
0.5 MV/cm and 0.16 T, respectively, excites both modes of spin resonances in the weak …

We investigate the role of domain walls in the ultrafast magnon dynamics of an
antiferromagnetic NiO single crystal in a pump-probe experiment with variable pump photon …
