Abstract	In this report the magnetic behavior and magnetocaloric response of the intermetallic compound Dy5Pd2 has been investigated from detailed magnetization measurements. Magnetic cluster glass behavior has been observed in the crystalline Dy5Pd2 compound below 38 K. Magnetocaloric entropy changes evaluated using Maxwell’s relation (MXR) from zero-field-cooled magnetization isotherms, which is used mostly in the literature, shows a giant inverse magnetocaloric effect (MCE) below 20 K and a large conventional MCE around 60 K in this compound. The observed value of inverse MCE is ∼29 J kg−1 K−1 for 50 kOe external magnetic field change at T = 3.5 K. In this context, the origin of the giant inverse MCE and its temperature dependence has been studied. The applicability of MXR and procedure to obtain reversible MCE using MXR which is important for practical application has been discussed. Dy5Pd2 exhibits a reversible MCE with a peak value of magnetic entropy change (ΔSmaxM) 8.3 J kg−1 K−1 at 60 K under a magnetic field of 50 kOe and an irreversible inverse MCE below 20 K.
