Title [sv]
Ultrasnabba icke-jämvikters processer i magnetika material och i spinntronik
Title [en]
Ultrafast Non-Equilibrium Processes in Magnetic Materials and in Spintronics
Abstract [en]
Ultrafast laser control of magnetism is a novel research field which encompasses both basic research and potential applications. Here, ultra-short laser pulses are used to trigger the generation of a spin-reorientation or an ultrafast spincurrent. These ultra-short laser pulses (in the femtosecond range) are the shortest man-made tools that allow for novel ways to control and manipulate the magnetic structure and spin-transport on hitherto unthought-of time-scales.Spintronics is a flourishing research field in its own right. It is a promising alternative to currently existing charge-based electronic technology; it aims to achieve an active control and manipulation of spin degrees of freedom in solid-state systems. Thus, it appears that ultrafast THz control of magnetism is a natural partner to novel ultrafast spintronics operating with laser-induced femtosecond spin current pulses.In this project I intend to develop foundational theory for ultrafast non-equilibrium laser-induced magnetic processes. Particularly, the stimulation of magnetic material with an optical pulse and the fundamental couplings between the electronic, spin and ionic degrees of freedom will be theoretically investigated. This is a novel route that remains largely unexplored theoretically and that will pave the way to gain a complete understanding of the magnetization dynamics. It can be expected that this project will contribute for advancing technological applications.
