Abstract

The magnetic behavior of a decagonal quasicrystal Al40Mn25Fe15Ge20 system has been investigated by Mössbauer spectroscopy, magnetization and AC susceptibility measurements. Magnetization measured at low fields as a function of temperature shows a cusp-like peak around 41 K. AC susceptibility also shows a sharp cusp, and the cusp shifts to a higher temperature as the frequency increases. These results strongly suggested that Al40Mn25Fe15Ge20 is a spin glass system with Tg = 41 K. From the temperature dependence of the Mössbauer spectrum, we observed the appearance of a hyperfine field below around 50 K. The temperature is a little higher than the cusp temperature, which is rather usual in spin glass systems.
