Abstract A novel metastable phase of DyGe 2.85 synthesised in the AuCu 3 -structure under high pressure, has been studied by means of the magnetic susceptibility and electrical resistivity measurements (under the pressure P ≤ 3.1 GPa), neutron powder diffraction and time-differential γ - γ perturbed angular correlations (TDPAC) using 111 Cd nuclear probes. Two distinct phase transitions have been found in this compound as the temperature is lowered. We assign the first transition occurring at the temperature T CDW = 80 K with charge density wave formation and the second transition at T N ≈ 18 K with an antiferromagnetic spiral ordering of Dy magnetic moments, and discuss a close relationship between them.
