Biography

Research Interest

I am interesting in ultra-thin magnetic thin films and more particularly on femtomagnetism. To probe the magnetization in such thin materials I am mainly using soft x-rays and XUV. The interactions between XUV/x-rays with matter allow to have a spatial resolution of the order of the nanometer, to be chemically selective and to be magnetic sensitive. Depending on the used geometry: in transmission, reflectivity or scattering one can be sensitive in depth, or in the sample plane. My favourite technique is to use x-ray Resonant Magnetic Reflectivity (XRMR) to probe the inhomogeneity of the magnetization in depth. To be time resolved I am using XUV/X-rays pulses of hundreds of femtoseconds provided by femtoslicing or Free Electron Laser (FEL) sources at SOLEIL, BESSY, LCLS, FLASH and FERMI.
