description: The subject of the graduate qualification work is Â«The effect of ultrafast laser induced heating on the indirect-exchange coupling of the RKKY in the Curie switch structuresÂ».
This work is devoted to studying magneto-optical response of the Curie switch under ultrafast laser induced heating. The research project included the following goals:
1. To measure magnetic hysteresis loops of the Curie switch samples Fe/Cr/FexCr1-x/Cr/Fe.
2. To determine the exchange coupling between ferromagnetic nanolayers in the Curie switch structure with different spacer doping with Fe.
3. To detect the Curie switch dynamic response to ultrafast laser induced heating.
4. To determine the dependence of the change of the exchange coupling between ferromagnetic nanolayers in Curie switch structure on the laser pulse fluence.
The work was performed at the Ferroic Physics Laboratory (Ioffe Institute). The calculation of the penetration depth for optical radiation into the structure was performed, the longitudinal magneto-optical Kerr effect depending on the external magnetic field applied in the sample plane and time delay between pump and probe pulses were measured. 
The obtained results allow us to suggest that the exchange coupling in the Curie switch structures increases under influence of ultrafast laser induced heating.
