Size effect on the magnetization and the coercivity of nanocrystalline Ni films has been examined at room temperature. Agreement between modeling predictions and measurements reveals that the size-suppressed magnetization results from the drop of spin-spin exchange energy due to the coordination number (CN) imperfection of atoms near the surface edges, and that the size-enhanced coercivity arises from intergrain interaction that is proportional to the inverse of particle size. Findings herewith and reported previously on the size-induced lattice contraction and Curie temperature suppression evidence the significance of atomic CN imperfection on the unusual behavior of a ferromagnetic nanosolid.

Incorporating the recent bond order-length-strength correlation mechanism [Sun et al., Acta Mater 2004;52:501] into the Ising convention and the Brillouin function has enabled the unusual magnetic behavior of a ferromagnetic nanosolid and a surface to be reproduced using Monte Carlo simulations. Examination of the size and temperature dependence of the saturation magnetization (MS) of a solid of various structures reveals that: (i) at low temperatures, the MS increases inversely with solid size due to the contribution from the localized charges that are trapped by the deepened potential well of the lower-coordinated atoms in the surface skins, (ii) at the ambient temperatures, the MS drops with solid size because of the bond order loss that suppresses the Curie temperature of the specimen, and (iii) the quantized features of the surface to volume ratio of the solid is responsible for the observed MS oscillations of smaller clusters at low temperatures.

onsistent insight into the size-enhanced E4f-level shift and the size-suppressed melting point of Au nanosolids has been obtained based on the bond order-length-strength (BOLS) correlation mechanism [Sun, et al, Acta Materialia 51, 4631 (2003)]. Consistency between theory predictions and observations reveals that the atomic-coordination number (CN) imperfection induced bond contraction and the associated bond-energy increase dictate these changes. The increase of binding energy density per unit volume in the relaxed surface region perturbs the Hamiltonian that determines the core level shift; the decrease of atomic cohesive energy (a product of atomic CN and the single bond energy) determines the thermal energy required for melting. Extending the knowledge to the lower end of the size limit suggests that the metallic bond in the gold monatomic-chain contracts by ~30% associated with ~43% magnitude rise of the bond energy. The crystal binding intensity contributing from all the atoms i
