      abstract     = {Employing ab initio electronic structure calculations, we
                      investigate the conditions for spin-gapless semiconducting
                      (SGS) behavior in the inverse Mn2 CoAl Heusler compound. We
                      show that tetragonalization of the lattice, which can occur
                      during films growth, keeps the SGS character of the perfect
                      cubic compound. On the contrary, atomic swaps even between
                      sites with different local symmetry destroy the SGS
                      character giving rise to a half-metallic state. Furthermore,
                      the occurrence of Co-surplus leads also to half-metallicity.
                      Thus, we propose that in order to achieve SGS behavior
                      during the growth of Mn2 CoAl (and similar SGS Heusler
                      compounds) thin films, one should minimize the occurrence of
                      defects, while small deformations of the lattice, due to the
                      lattice mismatch with the substrate, do not play a crucial
                      role.},
