摘要
Using high magnetic field ESR spectroscopy we have performed resonance measurements of LiNiO2 up to 245 GHz between 4 and 300 K. For the first time we have detected separately the ESR spectra due to the Ni3+ ions in LiNiO2 matrix and the extra-nickel magnetic clusters. This allows us to make a detailed analysis of the magnetic properties of LiNiO2. (C) 1998 Elsevier Science B.V. All rights reserved.
