We discuss the ferromagnetic phase of the planar Kondo lattice model using the bond fermion technique. For sufficiently small Kondo exchange we find a weakly ferromagnetic phase already for the weakly doped Kondo insulator. We present the phase diagram of the model and its quasiparticle band structure in the different phases.
