Demagnetization dynamics after noncollinear dual optical excitation
Sergii Parchenko, Matthias Riepp, Simon Marotzke +4
We explore the impact of optical excitation using two interfering ultrashort optical pulses on ultrafast magnetization dynamics. Our investigation focuses on Pt/Co/Pt multilayers a…
