Resumen:
Ab initio calculations analyze the properties of the G-type antiferromagnetic Sr2Co2O5 as a high-spin system. The description of the electronic structure is given; all the Co atoms are in a high-spin state with a small unquenched orbital angular momentum. Thermal analysis on a polycrystalline sample shows a magnetic phase transition at high temperatures.
