The antiferromagnetic structures of KCrF3, KMnF3, eF3, KCoF3, KNiF3, and KCuF3 were obtained by neutron fraction. The manganese, iron, cobalt, and nickel doufluonides exhibited an order in which the divalent 3d ion as coupled antiferromagnetically to its six nearest neighbors. In the chromium double fluonide, the magnetic structure consisted of ferromagnetic (001) sheets, coupled antiferromagnetically along the STA001! direction. No magnetic ning was observed in the neutron d fraction pattern copper double fluoride. The magnetic structures and served crystallographic distortions are discussed in of an indirect exchange mechanism and in terms of the crystal field theory, respectively. (auth)
