摘要
A theory of dynamic spin reorientation in an antiferromagnet irradiated by a femtosecond laser pulse has been developed taking into account both the nonthermal effect of the pulse due to the inverse Faraday effect and the thermal effect of the pulse. It has been shown that even a weak heating of the spin subsystem by the pulse can significantly enhance the reorientation effect. The possibility of applying this effect to increase the efficiency of the excitation of the spin oscillations has been considered.
