"tool to control X-ray-induced demagnetization. Using XSPIN, it is now possible, for a specific multilayer material, to adjust the parameters of the laser pulses (their energy, duration and intensity) so that demagnetization occurs on the spatial and/or temporal scale specified by the needs... ultrafast magnetic switches controlled by laser pulses. Another potential area of application seems to be dynamic computer memories"
