We report about the dephasing of the spins states in a Garnet film excited by femtosecond laser pulses. It is shown that magneto-optical four-wave-mixing signals are efficiently generated and controlled with an external static magnetic field. The self-diffraction of either two or three femtosecond pulses allows us determining independently the coherent response time ($T_2$ < 50 fs) and the population relaxation, which occurs in several steps. After the laser induced demagnetization, the spin… Expand

Femtosecond magneto-optical four-wave mixing in Garnet films
One of the goals of Femtomagnetism is to manipulate the magnetization of materials using femtosecond optical pulses. It has been shown in ferromagnetic films that a magneto-optical (MO) coherentExpand
