Spin dynamics induced by intense terahertz pulses are commonly observed by magnetooptical effects. Here, we show that magnetorefractive effect provides a second-harmonic magnon signal whose amplitude is comparably strong with the linear component, ma

We study the terahertz (THz) magnetic field pulse enhanced by a spiral-shaped antenna resonator (SAR). We deposit the SAR on the surface of a terbium-gallium-garnet crystal, which has a large Verdet constant, and measure the Faraday rotation angle fo
