Magnetism and Magnetic Materials


The low temperature magnetism of some magnets based on ferricenium cations and tetrahedral tetraholaferrate anions is discussed. Some of these materials behave as layered magnetic composites with distinctly different ordering temperatures for their respective anion and cation sublattices based on iron-57 Mössbauer spectroscopy and low-field DC magnetic susceptibility studies. Exemplary results are presented for the specific case of [Cp2Fe]+[FeBr4] and indicateTcritical (anion) ∼ 14 K, while Tcritical (cation) ∼ 2.5 K whereχM versusT suggests canted 3D-AF (likely Heisenberg) behavior for the former and 2D-Ising AF behavior for the latter.
