N2 - Magnetic, transport, thermal and magnetocaloric properties of the hexagonal ZrNiAl-type compounds PrPdIn and NdPdIn have been studied. The results indicate that both the compounds exhibit long-range ferromagnetic ordering with the transition temperature TC=11.2 and 34.3 K, respectively. For NdPdIn, an additional phase transition occurs at T0=18.3 K caused by the antiferromagnetic coupling. The magnetic entropy change of PrPdIn and NdPdIn, calculated from the magnetization data, shows a large peak around the temperature just above TC suggesting the evident magnetocaloric effect. Below TC, both samples show the irreversible temperature dependence of magnetization and the long time magnetic relaxation effect, which may be the consequence of the domain-wall pinning effect and/or the intrinsic magnetic frustration due to the non-collinear ferromagnetic spin structure.
