Erratum: "Ultrafast demagnetization by hot electrons: Diffusion or super-diffusion?" [Struct. Dyn. 3, 055101 (2016)].

[This corrects the article DOI: 10.1063/1.4964892.].

The total heat of the electron gas per volume was taken as , whereas the correct value is . The corrected diffusion equation reads The simulation was calculated correctly in the paper. In Section V (Analytical Model), the following equations need to be adapted accordingly: These changes affect the result of the analytical model presented in Figure 3. The correct model is in better agreement with the experimental data.

FIG. 3.

Amplitude dependence of the ultrafast demagnetization (red) and the non-magnetic contrast (blue) as a function of the absorber film thickness dAl, scaled by the pump pulse energy. The non-magnetic contribution follows the optical transmission. The demagnetization initially follows the non-magnetic signal but decays on a longer length scale of 23.5 nm for dAl > 30 nm. The inset shows the demagnetization time as a function of dAl for the measurement and the simulation.
