Switching of Magnetic Films by Femtosecond Laser Pulses and Control Spin Current

Spintronic belongs to one of the most the quickly developing area of science and technology, which is based on the control over the processes of transfer of spin current among the elements of electronic devices. To create high-spintronics, elements necessary reversing control the magnetic electrodes with high speed. Interestingly, the possibility of the magnetization control in heterogeneous magnetic nanostructures can be realized by picosecond and femtosecond laser pulses. Such short laser pulses allow geting a large spin current along a laser beam and inducing the effective internal magnetic field of the inverse magnetooptical Faraday effect provides ultra-speed magnetic switching in the magnetic nanostructures. This article presents the results of experimental studies of the dynamics of magnetization reversal by femtosecond laser pulses of a magnetic nanofilms with one or two the magnetic nanolayers and shows that by using ultrashort laser pulses, it is possible not only to study the dynamics and transport processes of the spin current in multilayer magnetic nanofilms, but also to control the spin transport in the spintronic elements.
