“…Magnetization switching and spin precession in magnetically ordered materials under optical pulses have been investigated extensively in the past decade. [1][2][3][4][5] On application of visible or near infrared femtosecond pulses to a magnetic structure, a transient magnetic field is generated through the inverse Faraday effect, 6,7 by which non-thermal magnetization control can be realized with optical pulses. 8,9 Coherent manipulation of spin precession with ultra-fast laser pulses have been studied extensively in a variety of materials, from ferromagnetic dielectric, 1,2 and ferromagnetic metal alloys 4,10 to paramagnetic dielectrics 11 and magnetic ionic liquids.…”

We present the magnetic dipole transition at 0.299 THz excited by magnetic component of terahertz electromagnetic pulse in an antiferromagnetic YFeO3 crystal. The impulsive magnetic field of the terahertz pulse tilts the macroscopic magnetization, causing deviation from the equilibrium position, which is manifested by a sharp absorption at the frequency of the quasiferromagnetic mode of the crystal. The rotating coherent macroscopic magnetization radiates elliptically polarized emission at the frequency of the quasiferromagnetic resonance due to the dichroic absorption in the crystal.

We present a femtosecond spectroscopic magneto-optical investigation of the coherent and incoherent spin dynamics in the antiferromagnetic dielectric KNiF 3 . The pathways of the photoinduced energy flow to spins were controlled by tuning the pump photon energy. In particular, we demonstrate that laser pulses, with photon energy tuned to a nearly-zero-absorption region, excite the spin system without any signatures of heating of electrons or phonons. In this regime the ultrafast excitation of coherent spin waves is followed by a gradual increase of the spin temperature solely due to decoherence of the laser-generated magnons, as revealed by our simultaneous measurement of both the transversal and the longitudinal component of the spin dynamics.

“…Since the spins in Cu 2 OSeO 3 are found to form a quantum triplet states within the Cu 4 tetrahedra2930, these spin dynamics would be better described by incorporating the quantum fluctuations. We note that the optical excitation can also generate “forbidden” spin resonances by using site-dependent magneto-optical susceptibilities31.…”

Magnetic skyrmions in an insulating chiral magnet Cu2OSeO3 were studied by all-optical spin wave spectroscopy. The spins in the conical and skyrmion phases were excited by the impulsive magnetic field from the inverse-Faraday effect, and resultant spin dynamics were detected by using time-resolved magneto-optics. Clear dispersions of the helimagnon were observed, which is accompanied by a distinct transition into the skyrmion phase, by sweeping temperature and magnetic field. In addition to the collective excitations of skyrmions, i.e., rotation and breathing modes, several spin precession modes were identified, which would be specific to optical excitation. The ultrafast, nonthermal, and local excitation of the spin systems by photons would lead to the efficient manipulation of nano-magnetic structures.
