A fast way of reversing the magnetization is precessional switching (top), where a short field pulse is applied perpendicular to the magnetization. If the pulse is properly shaped, it can rotate the magnetization by 180°. The faster “linear” switching mode described by Vahaplar et al. (bottom) is driven by a short and intense circularly polarized laser pulse. Shortly after the pulse, the magnetization collapses due to heating. During the cooling, restores along the effective magnetic field that is generated by the inverse Faraday effect.
