The results of time-dependent remanent magnetization (MIRM) behaviour (magnetic relaxation studies) in polycrystalline Gd2−xYxPdSi3 alloys in a magnetically ordered state are reported. We observed that MIRM undergoes slow relaxation with time. We have also measured ac susceptibility as a function of frequency; however, we did not find any upward shift of the peak-temperature with an increase of frequency, which suggests that these alloys are not spin-glasses. Measurements on single-crystalline Gd2PdSi3 show that the magnetic relaxation is an intrinsic property of the materials.
