Description
Summary:X-Ray diffraction and anisotropic magnetic measurements have been made on single crystals of lunar ilmenite and on terrestrial ilmenite from Bancroft, Ontario, Canada and the Ilmen Mountains, U.S.S.R. The elongated c -axis of lunar ilmenite, previously reported, is confirmed by new measurements. The shorter c -axis found in terrestrial specimens is ascribed to Fe 3+ substitution for Ti 4+ in the titanium layer. Magnetic measurements on the same specimens show that, in agreement with the Ishikawa-Shirane et al. model, the initial shortening of the c -axis by the above substitution of small amounts of Fe 3+ (
