Engineering Ultrafast Magnetism

Date Do, 25.02.2016 - Do, 25.02.2016
Time 10.00
Speaker Ilie Radu, Max-Born Institute Berlin and Helmholtz-Zentrum Berlin, BESSY II, Berlin, Germany
Location PSI, WBGB/019
Program Controlling magnetic order on ultrashort timescales is crucial for engineering the next-generation magnetic devices that combine ultrafast data processing with ultrahigh-density data storage. An appealing prospect in this context is the use of femtosecond (fs) laser pulses as an ultrafast, external stimulus to fully set the orientation and the magnetization magnitude of a spin ensemble. Achieving such control on ultrashort timescales, e.g. comparable to the excitation event itself, remains however a formidable challenge.
Here, I report on the latest developments in our studies on ultrafast magnetism, which reveal highly unexpected and very intriguing phenomena [2,3] by employing a novel experimental approach combining the fs laser excitation with an ultrafast, element-specific X-ray probing of spins. In particular, by investigating the laser-driven magnetization dynamics in ferromagnetic and ferrimagnetic alloys and heterostructures, we demonstrate a simple but powerful way of controlling the ultrafast spin dynamics in a large class of magnetic materials.
