The challenge is to produce magnetic NPs with high magnetic saturation without exceeding the super-paramagnetic limit so that they may be used as non-permanent magnets in biomedicine and catalysis. FePt offers enhanced saturation magnetisation properties compared to iron oxide, however synthetic methods require fine-tuning to achieve these superior properties. Multicore FePt NPs up to 44 nm in diameter and composed of Pt rich FePt nanocrystals within an iron rich FePt matrix not previously seen in the literature are presented here. The results indicate that coordination of Fe and Pt intermediates with oleic acid and oleylamine respectively hinders deposition of each respective metal in the growth of discrete and multicore NPs. date: 2014 official_url: http://dx.doi.org/10.1039/c3ra44319a vfaculties: VMPS oa_status: green full_text_type: pub language: eng primo: open primo_central: open_green verified: verified_manual elements_source: WoS-Lite elements_id: 915668 doi: 10.1039/c3ra44319a lyricists_name: Nguyen, Thanh lyricists_id: TTKNG00 full_text_status: public publication: RSC Advances volume: 4 number: 3 pagerange: 1039-1044 issn: 2046-2069 citation: Green, LAW; Thuy, TT; Mott, DM; Maenosono, S; Thanh, NTK; (2014) Multicore magnetic FePt nanoparticles: controlled formation and properties.
