摘要：

Magnetization measurements were performed from 5 to 300 K on nanocomposite compounds obtained by precipitation of MoS2 single-layer dispersion in the presence of Co2+ or Ni2+ ions. Ni(II) and high spin Co(II) were evidenced, both in octahedral oxygen surrounding. From similarity of their temperature magnetic behavior with that of lamellar references Ni(OH)(2) and beta-Co(OH)(2) powders, it can be inferred that the nanocomposites contain 2D nickel or cobalt hydroxide species. The low temperature magnetic behavior is discussed on the basis of dimensionality and finite particle size effects. (C) 1997 Elsevier Science Ltd.
