Ultrafast magnetostructural dynamics of MnAs
Due to its magnetostructural phase transition, MnAs is a paradigmatic material for studying the strong coupling between lattice and magnetism. Here, the authors explore the subpicosecond magnetic and structure dynamics of MnAs following laser excitation in order to test the transition mechanisms proposed in the literature. Time-resolved x-ray diffraction measurements reveal a differentiation of Mn and As atomic disorder relaxation times in the ferromagnetic phase that is absent in the paramagnetic phase. These results strongly support the predictions of recent density functional theory calculations.
