dc.description.abstractNanostructured Co with large lattice extension and contraction was produced by electrodepositing Co on nanoporous Au. The Co deposited showed a low magnetic saturation of 76 emu/g and a high coercivity of 462 Oe. First-principles calculations showed that the magnetic moment of a Co atom is significantly decreased by lattice contraction. Therefore, the noteworthy magnetic properties of the Co deposited are attributed to the large lattice strain. Also, molecular dynamics simulation showed that the lattice extension and contraction of about 10% are generated in the overall Co crystal. This is in agreement with the experimental results of HRTEM observation. The constraint of the movement of Co atoms by the concave structure of nanoporous Au leads to a wide spread of large strain region.en
