      abstract     = {The ultrafast dynamics of 𝛼-MnAs magnetization and
                      atomic structure are studied by the time-resolved
                      magneto-optical Kerr effect and time-resolved x-ray
                      diffraction after photoexcitation. In the basal plane of the
                      hexagonal unit cell, Mn atomic disorder increases on a
                      timescale of 400 fs, comparable to the laser-induced
                      demagnetization timescale and significantly faster than As
                      disorder (700 fs). This differentiation of the Mn and As
                      relaxation times is observed in the ferromagnetic phase but
                      disappears in the paramagnetic phase. These results strongly
                      support recent density-functional theory calculations
                      predicting that the magnetostructural phase transition of
                      MnAs is driven by a change in nature of the dominant
                      interactions between Mn 3⁢𝑑 electrons, from magnetic
                      exchange to bonding interactions.},
