Time resolved measurements of the linear magneto-optical Kerr rotation revealthat, in the {\it 3d} ferromagnets Fe, Co and Ni, the amplitude of thedemagnetization increases linearly with the fluence of the light. Werationalize this phenomenon as being linearly driven by the increase intemperature, the electron-phonon and electron-magnon scattering, and areduction of the inter-atomic exchange. The amplitude of the latter phenomenon,which until the present study has been widely overlooked, is obtained through\textit{ab initio} density functional theory calculations, and is argued to bethe principal source of demagnetization in Ni and Co, while still contributinglargely in Fe.

Uncovering the role of the light-induced reduction of the inter-atomic exchange in the ultrafast demagnetization of Fe, Co, and Ni
