Keywords: | Antiferromagnetism;Mott localization;NMR - Knight shift | Issue Date: | 1-Jan-2001 | Journal: | Journal of Magnetism and Magnetic Materials | Abstract: | We report 27Al-NMR and DC-magnetic susceptibility measurements on recently discovered alkali-electro-sodalite (AES, A = Sodium, Potassium). AES is known to be a Mott insulator consisting of a body-centered-cubic lattice of F-centers. 27Al-NMR measurements demonstrate that SES (S = Sodium) and PES (P = Potassium) undergo an antiferromagnetic transition around TN ∼ 48 and 70 K, respectively. Magnetic properties, especially on the temperature dependence of the susceptibility, seem to be quite sensitive to the size of the F-centers. © 2001 Elsevier Science B.V. All rights reserved. |
