Abstract
We report three new paramagnetic centers found in high-pressure synthetic d iamond with high nitrogen and nickel content and annealed at 1600 degrees C . Analysis of the spectra has shown that two of the centers, labeled AB1 an d AB2, are related to systems with effective spin S=1/2 and the other is re lated to a system with spin S=1 (AB5). All these centers have trigonal symm etry. The possible relation of these centers with nicker is discussed. (C) 2000 Elsevier Science S.A. All rights reserved.
