摘要：

3d based double perovskite (DP) oxides having great research interest due to their physical properties with some great technological application. Magnetodielectric, magnetocaloric effect, ferroelectric, exotic magnetic phases etc are some properties that double perovskite materials shows, thus received attention of researchers. Magnetic refrigeration is the great cooling technology based on magnetocaloric effect due to high energy efficiency and environmental friendly. Recently, it is found that Gadolinium (Gd) have magnetic refrigerant properties because of large magnatochloric effects at room temperature. In this paper we present the double perovskite Gd2CoMnO6 nano-crystalline which was prepared by sol gel method and its magnetic properties studied by vibrating sample magnetometer (VSM). There is a paramagnetic to ferromagnetic phase transition observed in the sample. We found that paramagnetic Curie-Weiss temperature of Gd2CoMnO6 is around T-c = 131.27 K. Further, temperature dependent inverse magnetic susceptibility (chi(-1)) shows deviation from curie Weiss behavior around T-G similar to 213 K which is depicts that Griffiths phase singularities is present in this material.
