    • We note that the in-plane applied field component needs to exceed ∼120 kA/m in order to induce a single domain state in the sample. A further field increase has a similar effect as increasing the pump fluence above the AFM-FM threshold, consistent with the static measurement showing that the applied field reduces the transition temperature [21].

    • K(t). In our configuration the initial growth of the magnetization will be accompanied by a strong increase of the demagnetization field. Such a rapid variation in the effective anisotropy field is known to give rise to precessional motion of the magnetization [20], However, we carefully verified that including this effect does not affect our conclusions regarding the rapid transformation during the first tens of ps.

    • K) that would be expected for the case with a significant electronic contribution. This leads to the conclusion that the dominant contribution to the AFM-FM phase-change induced ΔR is from the transition-driven lattice expansion.

    • note
    • The subtraction based on linear scaling is further justified by the fact that the linear relation between the hot electron peak and the pump fluence is still maintained above the transformation threshold.
