• Monte Carlo simulation was performed to study the magnetism in the double perovskite Sr2CrOsO6.
• Ground state phase diagram has been established regarding different crystal field values.
• Size effect on the magnetic properties has been analyzed.
• Effect of the crystal field of Osmium on the thermal behavior has been explored.

Sr2CrOsO6 double perovskite (DP) has been gaining importance in recent years thanks to its high ordering temperature (Tc=725 KTc=725 K) that is the highest TcTc measured among all DPs so far. Spin-polarized (5d t2g)-orbital of Os-atoms is completely filled, which allows the compound to be considered as fully spin-polarized exactly at the limit of the metal–insulator transition. This interesting property gives the compound exceptional properties and more ability to use in spintronic applications. In this paper, the energetic and the magnetic behavior of this material have been explored using Monte Carlo Simulation (MCS) within the framework of Ising model. Ground state phase diagram has been dressed and analyzed. Size effect on the magnetic properties has been analyzed. Effect of the crystal field of Osmium on the thermal behavior has been explored. Critical exponents have been calculated, discussed regarding the crystal field of Osmium and evaluated against the universality class.
