Abstract

We have carried out powder neutron diffraction experiments on the recently discovered Cd-Mg-Tb quasicrystal. Magnetic long-range order was not detected down to 2.5 K. Instead, short-range correlations develop continuously as temperature is decreased below the spin freezing temperature T_f1 = 12.5 K; no discontinuous change was observed at T_f2 = 5.6 K, where an additional anomaly was found in magnetic susceptibility. The short-range order is mostly identical to that observed in the Zn-Mg-Ho quasicrystal.
