Journal ArticleDOI
Observation of coupled magnetic and electric domains
TL;DR: Spatial maps of coupled antiferromagnetic and ferroelectric domains in YMnO3 are obtained by imaging with optical second harmonic generation and lead to a configuration that is dominated by the ferroelectromagnetic product of the order parameters.
Journal ArticleDOI
Ultrafast non-thermal control of magnetization by instantaneous photomagnetic pulses.
TL;DR: It is demonstrated that circularly polarized femtosecond laser pulses can be used to non-thermally excite and coherently control the spin dynamics in magnets by way of the inverse Faraday effect, and offers prospects for applications of ultrafast lasers in magnetic devices.
Journal ArticleDOI
Laser-induced ultrafast spin reorientation in the antiferromagnet TmFeO3.
TL;DR: It is shown that, using a short laser pulse, the spins of the antiferromagnet TmFeO3 can indeed be manipulated on a timescale of a few picoseconds, in contrast to the hundreds of picoseConds in a ferromagnets.
Journal ArticleDOI
Second-harmonic generation as a tool for studying electronic and magnetic structures of crystals: review
TL;DR: Second-harmonic generation (SHG) in magnetically ordered crystals is reviewed in this article, where the specific degrees of optical experiments -including spectral, spatial, and temporal resolution - lead to the observation of novel physical effects that cannot be revealed by other techniques of probing magnetism.
Journal ArticleDOI
Inertia-driven spin switching in antiferromagnets
TL;DR: In this article, the authors demonstrate an inertia-based spin switching mechanism in antiferromagnets, where the exchange interaction between the spins leads to an inertial behavior, such that only a short "kick" is required to transfer sufficient momentum to the spin system for it to reorient.
