    • It is well known that ferromagnetism in transition metals is promoted by the Hund’s rule exchange (Formula presented). Its mechanism is, however, different from that pointed out by Kugel and Khomskii for transition metal oxides [K. I. Kugel and D. I. Khomskii, Sov. Phys. Usp. 25, 231 (1982)]. While local moments form in partially filled orbitals of transition metals, a particular orbital ordering suppresses the antiferromagnetic superexchange and promotes weak ferromagnetic interactions between Cu(Formula presented) ions in KCuF(Formula presented).
