We present the investigation on the magnetocaloric effect (MCE) in an orbital-spin-coupled spinel vanadate Mn0.95Zn0.05V2O4 via the dc magnetization and the specific-heat measurements. The maximum values of magnetic entropy change of Mn0.95Zn0.05V2O4 reach 9.6 and 16.5 J/kg K for field change 0–4 T around ferrimagnetic ordering temperature TC=52.5 K and orbital ordering temperature TOO=45 K. Except for a small quantity of contribution of the spin entropy, the observed giant MCE around TOO may be attributed to the orbital entropy due to the change of the orbital state of V3+.
