Abstract

The availability of ultrafast-pulsed light sources has enabled the fast developments of apparatus for studying magnetism on ultrafast timescales. Femto-/picosecond spin-dynamics measurements provide important insight for underlined mechanisms on spin–electron–lattice scattering processes, which is also essential for magnetic storage technologies. This review provides experimental details of various time-resolved pump–probe techniques used for spin-dynamics studies. This includes laser-pumped and magnetic field-pumped setups with magneto-optical Kerr effect (MOKE) and X-ray magnetic linear dichroic (XMLD) effect, accompanied by the example results for each technique discussed.
