Pump-probe photoemission photographs optical quenching of magnetization in iron as a thermal process
The research team of Sprint laboratory at CNR-IOM in Trieste revealed the prevailing thermal nature of light-induced ultrafast demagnetization in the regime of low perturbation, by means of pump-probe photoemission spectroscopy. Despite similar findings were evidenced in previous research, up to now few works had employed photoemission spectroscopy, which allows a direct insight on the electronic temperature and on the magnetic moment at the Fermi level during the ultrafast process.
