“…The optical field of ultrafast laser pulse can couple with the spin and orbital angular momentum of electrons that can modify the effective spin–orbit interaction . The ultrafast laser heating can cause weakening of spin–orbit coupling . In the present scenario, the increase in laser fluence weakens the spin–orbit interaction that results in changes in τ e–s and τ s–l , which presumably influences the demagnetization as well as the damping of the precessional motion in an opposite manner.…”

The electrochemical growth of Heusler alloy film with good morphological quality and crystalline order using singlecrystalline substrate is demonstrated. Static magneto optical Kerr effect studies are employed to reveal the surface magnetization reversal of the films. An understanding of the intrinsic nature of the magnetization dynamics in this class of electrochemically grown materials is presented using time-resolved magneto optical Kerr effect measurements, under femtosecond laser excitation. Excitation laser fluence dependence study reveals the ultrafast demagnetization time, fast remagnetization time, and magnetic damping parameter as well as their correlation.
