摘要：
We have observed terahertz radiation from coherent antiferromagnetic magnons excited by circularly polarized laser pulses. The polarity of the magnons is reversed by switching the helicity of the circular polarization. Inverse Faraday effect is a possible mechanism of the coherent magnon excitation.
