      abstract     = {Metadislocations are novel defects recently identified in
                      complex metallic alloys. It was reasoned that their
                      propagation necessarily requires the orchestrated motion of
                      hundreds of atoms along various crystallographic directions
                      per elementary step. Here, we report on the direct
                      observation of the motion of metadislocations on the atomic
                      scale in the complex metallic alloy phase T-Al-Mn-Fe, using
                      in-situ high-resolution transmission electron microscopy. We
                      observe their propagation by discrete jumps between
                      low-energy configurations. Using a tiling model, we
                      determine their characteristic features including the
                      Burgers vector, and identify their motion to take place in a
                      mixed glide/climb process.},
