Hysteresis behavior of CoPt nanoparticles

Cobalt Ion Mediated Self-Assembly of Genetically Engineered Bacteriophage for Biomimetic Co−Pt Hybrid Material

“…The stripe patterns observed on the bundles are ∼6 nm in width, close to the diameter of a phage particle. The selected area electron diffraction (SAED) pattern shows the fundamental ring pattern of fcc CoPt . A HRTEM image (Figure e) shows the lattice fringe of the nanoparticles, indicating their crystalline nature.…”

Nanocomposite Co1-xPtx:C films for extremely high-density recording

“…Since the coercivity is closely related to the mag- [8]. Experimental results showed that the standard CoPt L1 0 phase is of a fct structure and a very high anisotropy (up to 4.9 × 10 7 erg/cm 3 ) [9]. Therefore, the CoPt:C film of composition approaching to the standard L1 0 phase will have a high coercivity.…”

Synthesis of L10 ferromagnetic CoPt nanopowders using a single-source molecular precursor and water-soluble support

“…2 CoPt alloy nanoparticles are also known to function as chemical CO oxidation catalysts 4 and as electrochemical catalysts for CO or methanol oxidation. 5 CoPt nanoparticles of near 1 : 1 alloy stoichiometry have been prepared via hydrogen reduction, 6,7 borohydride reduction, [8][9][10][11][12] polyol reduction, [13][14][15][16][17][18] sol-gel methods, 19,20 reverse micelle methods, 21,22 galvanic displacement, 23 evaporation methods, [24][25][26][27] ion-beam depositiom, [28][29][30] pulse-laser-deposition/ ablation/sputtering methods, [31][32][33][34][35] or by bio-inspired or biomimetic methods. 36,37 Common to these methods is use of separate sources of Co and Pt and a two-step process entailing formation of CoPt nanoparticles with subsequent thermal annealing.…”
