"Dynamic magnetic imaging using a femtosecond pulsed laser"

Liat Szapiro 
Dept. of Condensed Matter Physics, Tel Aviv University


     Measurements of magnetic hysteresis, a short time after the ferromagnetic sample is excited by a femtosecond laser pulse, show a decrease of the coercive field that can be understood as a local rotation of the magnetization in the part of the sample that was affected by the pulse. We built an imaging system that can follow the changes in the magnetic structure of the sample across the hysteresis loop, and in particular can show the local magnetization rotation. The Imaging system, based on illumination by a femtosecond pulse, opens the way to time resolved experiments and measurement of the magnetization switching time.
