Circular dichroism experiments at the <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mrow><mml:mi>L</mml:mi></mml:mrow></mml:math> edge of magnetic transition metals enabled by elliptically polarized pulses from a seeded free-electron
The authors demonstrate the generation of elliptically polarized femtosecond pulses from a seeded free electron laser (FEL) in the 700--800 eV range. Using a variable-polarization undulator, they achieved on-axis elliptical polarization at the third harmonic of FEL's fundamental wavelength, enabling studies based on magnetic circular dichroism at the Fe ${L}_{2,3}$ edge. These results pave the way for investigations of transition metals, covering both the $M$ and $L$ edges at the FERMI FEL at Elettra Sincrotrone Trieste.
