Abstract
We report on the first observation of the Y-89 NMR signal in the hexagonal trideuteride phase YD2.98 at 14.7 MHz (7.04 T) and 302 K. In this phase the Y-89 nuclei are in an environment characterized by the shift tensor components delta(iso) = 361. delta(aniso) = 90 ppm and eta(s) approximate to 0.1. The spin-lattice relaxation time is estimated to be of the order of 7 x 10(3) s at 302 K. Magnetic measurements show that the magnetic susceptibility is small and diamagnetic in the temperature range 1.8-300 K. For comparison, the Y-89 NMR and susceptibility data for yttrium metal and its dideuteride phase YD1.99 are also given and discussed. (C) 2002 Elsevier Science Ltd. All rights reserved.
