Magnetic and 57Fe Mössbauer measurements are reported on Taylor-phase compounds T-Al3Mn(Pd,Fe), which are complex metallic alloys containing 156 atoms in the unit cell. These investigations are extended to Al71Mn19Fe10 which crystallize as decagonal quasicrystal. Common for all samples spin glass behavior is present at low temperatures with freezing temperatures Tf increasing (decreasing) with Fe (Pd) content. Below Tf rejuvenation and memory effects are observed in aging investigations. Above Tf the 57Fe Mössbauer spectra were analysed by a superposition of two subspectra with intensity ratio around 75:25, which might be allocated to Fe substituted on Mn sites surrounded either by Al and Mn or completely by Al in the nearest neighborhood. Below Tf broad hyperfine field distributions are present.
