  • The magnetism produced by electrons in a solid can have two components — the spin and orbital moments — that are interchangeable on femtosecond timescales. Here it is shown how rapid changes in these two components can be disentangled, providing insights into the underlying dynamical processes that could be of value for the ultrafast control of information in magnetic recording media.

  • Femtosecond laser pulses can induce ultrafast changes to the magnetization in magnetic materials. Here, the authors show that the ultrafast demagnetization in ferrimagnets is driven by the transfer of angular momenta between two coupled sublattices whilst the total angular momentum remains constant.
