✦ Synopsis

Murdochite-type (Ni 6؊x Cu x )MnO 8 (0.04x40.4) was synthesized at 873 K using the precursor method. Both the (Ni, Cu)-O(1) and Mn-O(1) distances increase slightly with increasing x. These increases depend on the difference between the ionic radii of the Ni 2؉ and the Cu 2؉ ions. The magnetic measurement indicates that the 1/ -T curve has a step caused by the mixture of the antiferromagnetic cluster due to the 180°superexchange interaction for (Ni 2؉ , Cu 2؉ )-O-(Ni 2؉ , Cu 2؉ ) and the paramagnetic spins.

All-electron, spin-polar&d, LCGTG-LDF calculations have been performed on Ni clusters with face-centered-cubic (and simple cubic) geometry. The results are discussed in relation to theoretical and experimental data for gas-phase Ni clusters and for the extended metal. We analyze bonding, magnetic be
