This material is known from various experiments to be ferromagnetic with a Curie temperature of 260$\\,$K to 305$\\,$K and a magnetic moment of 1.5${\\,\\mu_\\text{B}}$ to 3.0${\\,\\mu_\\text{B}}$. Applying the magnetic force theorem as it is formulated within Green's function method, we calculated for SrCoO$_{3-\\delta}$ the magnetic exchange parameters and estimated the Curie temperature.
