Research Abstract

Spin precession frequency of antiferromagnets reaches THz order, far above that of ferromagnets, indicating possibility of ultrafast magnetic recording. In this research, we have performed magneto-optical pump-probe experiment for non-thermal spin manipulation by circularly polarized pulse in antiferromagnetic NiO. We have observed oscillations with frequencies of 1.1 THz and 140 GHz that correspond to antiferromagnetic resonance frequencies of NiO. This results was interpreted as the inverse Faraday effect inducing spin oscillations which was triggered by an effective magnetic field in a sample by circularly polarized light.
