MagneDyn

Welcome to MagneDyn

The MagneDyn beamline at FERMI enables experimental access to the transient magnetic states of matter, opening unprecedented opportunities in the fields of femtomagnetism, spintronics, strongly electron and magnetic correlated systems, carbon based materials. The beamline exploits the time structure, full coherence, variable polarization and harmonic content/multi-color operation of the FERMI FEL source. The most prominent techniques that are available are core level MOKE effect and core level elastic/inelastic scattering.
Pump-and-probe experiments are carried out using the FEL alone or in combination with a synchronized optical laser (SLU).
These methods allow us studying the ultrafast magnetodynamics of the target system upon electronic and crystal excitations.

the X-Wollaston Polarimeter

The X-Wollaston (TONIX) polarimeter is capable of measuring the FEL pulse polarization status in single-shot mode. It works on a broad energy range from 50 eV to 150 eV, with extinction ratio higher than 40 in all the energy range. Successful commissioning had being achieved by measuring the element sensitive Kerr rotation at the Ni-edge in ferromagnetic Nickel.

the EUV Polarimeter

While in the visible range there are several devices -polarimeters- that can detect the polarization state of light waves, in the EUV (Extreme Ultraviolet) range polarimeters are lacking, slow and not very efficient. For this reason, we developed a polarimeter capable of single-pulse linear polarization angle detection in the EUV energy range.  A. Caretta et al., Structural Dynamics 8, 034304 (2021)
