Magnetic phases in a minimal model for kagome magnets are studied within the spatial dynamical mean field theory. The minimal model consists of a tight binding hopping and anisotropic double exchange on the kagome lattice. The spacial dynamical mean field theory is applied to 27 sites of the kagome lattice. A magnetic phase transition from out-of-plane ferromagnetic to in-plane antiferromagnetic phases occurs at finite temperature. There is a finite temperature range where both the out-of-plane ferromagnetic and the in-plane antiferromagnetic phases coexist.
