Chemical Ordering in Bimetallic FeCo Nanoparticles: From a Direct Chemical Synthesis to Application As Efficient High-Frequency Magnetic Material 2019 Access copy available to the general public Unrestricted Single-crystalline FeCo nanoparticles with tunable size and shape were prepared by co-decomposing two metal-amide precursors under mild conditions. The nature of the ligands introduced in this organometallic synthesis drastically affects the reactivity of the precursors and, thus, the chemical distribution within the nanoparticles. The presence of the B2 short-range order was evidenced in FeCo nanoparticles prepared in the presence of HDAHCl ligands, combining 57 Fe Mössbauer, zero-field 59 Co ferromagnetic nuclear resonance (FNR), and X-ray diffraction studies. This is the first time that the B2 structure is directly formed during synthesis without the need of any annealing step. The as-prepared nanoparticles exhibit magnetic properties comparable with the ones for the bulk (M s = 226 Am 2 ·kg -1 ). Composite magnetic materials prepared from these FeCo nanoparticles led to a successful proof-of-concept of the integration on inductor-based filters (27% enhancement of the inductance value at 100 MHz). info:eu-repo/grantAgreement/ES/MINECO-AEI-FEDER/MAT2016-79776-P info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 11.238 2019 CHEMISTRY, PHYSICAL 18 / 158 = 0.114 2019 Q1 T1 MATERIALS SCIENCE, MULTIDISCIPLINARY 25 / 314 = 0.08 2019 Q1 T1 NANOSCIENCE & NANOTECHNOLOGY 14 / 103 = 0.136 2019 Q1 T1 PHYSICS, CONDENSED MATTER 8 / 69 = 0.116 2019 Q1 T1 CHEMISTRY, MULTIDISCIPLINARY 19 / 177 = 0.107 2019 Q1 T1 PHYSICS, APPLIED 11 / 154 = 0.071 2019 Q1 T1 5.786 2019 Bioengineering 2019 Q1 Chemistry (miscellaneous) 2019 Q1 Nanoscience and Nanotechnology 2019 Q1 Materials Science (miscellaneous) 2019 Q1 Mechanical Engineering 2019 Q1 Condensed Matter Physics 2019 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Lepesant, M.
