      abstract     = {The mu-Al4Mn complex intermetallic phase with 563 atoms in
                      its giant unit cell exhibits a complicated temperature
                      dependence of electrical resistivity that has a broad
                      maximum at about 175 K and a minimum at 13 K. The
                      temperature dependence of the resistivity was reproduced by
                      employing the theory of quantum transport of slow charge
                      carriers, which predicts a crossover from the metallic
                      (Boltzmann-type) positive-temperature-coefficient electrical
                      resistivity at low temperatures to the insulator-like
                      (non-Boltzmann) negative-temperature-coefficient resistivity
                      at elevated temperatures. The low-temperature resistivity
                      minimum was reproduced by considering it as a magnetic
                      effect due to increased scattering of the conduction
                      electrons by the Mn spins on approaching the spin glass
                      phase that develops below the spin freezing temperature T-f
