A novel type of sub-lattice of the Jahn-Teller (JT) centers was arranged in Ti-doped barium hexaferrite BaFe 12 O 19 . In the un-doped crystal all iron ions, sitting in five different crystallographic positions, are Fe 3+ in the high-spin configuration (S = 5/2) and have a non-degenerate ground stat...
