Also reported here is a tunable synthetic method, in which the overall shape of the crystal is determined by a balance of kinetically and thermodynamically controlled growth mechanisms. The graphic shows one example of the degree of ordering available in the crystalline through this method. |

Enhanced Magnetic Transition of Core-Shell Cobalt-Platinum Nanoalloys
MRS Online Proceedings Library Archive, 721, 58 (Feb 1, 2002) DOI : https://doi.org/10.1557/PROC-721-E5.8Synthesis of ‘solid solution’ and ‘core-shell’ types of well defined Co-Pt based nanoalloys smaller than 10nm have been achieved by redox transmetalation reactions. This redox transmetalation are selectively observed only if the redox potential between two metals is favorable. The composition of the magnetic alloys can also be tuned by adjusting the ratio of reactants. Annealed core-shell nanoparticles transformed into mixed nanoalloys with face centered tetragonal (fct) structures, which show large coercivity and ferromagnetism at room temperature. These nanoparticles can potentially be used as an independent single magnetic bit of tera-bit information storage. Also, this kind of redox transmetalation reaction can be utilized as a general process to synthesize various types of nanoalloys with controlled composition in a selective fashion. |
