      abstract     = {Complex metallic alloys (CMAs) represent a class of
                      materials which are based on crystal structures with
                      exceptionally large unit cells comprising up to more than a
                      thousand atoms. As a result of the structural attributes of
                      these phases, their plastic deformation behaviour features
                      significant differences to conventional mechanisms known
                      from structurally simple materials. In the present work, the
                      plasticity of the three CMA phases, hexagonal μ-Al-Mn,
                      body-centred cubic Mg$_{32}$(Al,Zn)$_{49}$, and face-centred
                      cubic $\beta$-Al-Mg was investigated. Uniaxial deformation
                      experiments on single crystalline samples of these alloys
                      were carried out and thermodynamic activation parameters of
                      the deformation processes were determined. Microstructural
                      investigations by means of transmission electron microscopy
                      (TEM) were carried out on μ-Al-Mn and
                      Mg$_{32}$(Al,Zn)$_{49}$. The underlying deformation
                      mechanisms of these phases were completely determined.
                      Dislocation climb and associated diffusion of vacancies was
                      found to play an essential role in the deformation processes
                      of both materials.},
