Abstract

Few-cycle intense THz pulses and the process of the second harmonic generation are appealing techniques for excitation and investigation of ultrafast dynamic response of magnetically ordered systems, ferroelectrics and multiferroics at the picosecond timescale. In this study, we report on experimental findings on the optical second harmonic generation in the centrosymmetric antiferromagnetic NiO induced by intense THz pulses with electric fields up to 20 MV/cm.
