Band structure calculations show that the magnetic moments, at 0 K, for Ni (2c) and (3 g) sites decrease when increasing Ni content and are nil for x congruent to 2. XPS measurements, at room temperature, show the presence of unfilled Ni3d band in the entire composition range, in agreement with paramagnetic studies. The magnetic behaviour of nickel is analysed in models which take into account the electron cot-relation effects in d bands. (c) 2004 Elsevier B.V. All rights reserved. |
