Presentation

L’IRSAMC (The Institute of Research on Complex Atomic and Molecular Systems) is a federation of four laboratories (LCAR, LCPQ, LPCNO, LPT), in physics and fundamental chemistry whose research activities are supported both by the Université Paul Sabatier, the CNRS and INSA

Publications of 4 research laboratories

  • Hal-LCAR. - Laboratory Collisions Clusters Reactivity, from 1990 until todays
  • Hal-LCPQ. - Quantum Chemistry and Physics Laboratory, from 2007 until todays
  • Hal-LPCNO. - Physics and Chemistry of Nano Objects Laboratory, from 2006 until todays
  • Hal-LPT.- Theoretical Physics Laboratory, from 2003 until todays

Main advantages and functioning of Hal

Main advantages

  • Long-term archiving, sustainability of the deposits
  • Better visibility of the scientific productivity
  • Open access, accessible everywhere
  • Possibility of establishing lists of publications

Functioning

  • The deposit of a document requires the agreement of its authors, and it must respect editor policy.
  • If no agreement has been spent, deposit only the bibliographical note
  • Beware ! Once a document is put online, it cannot be withdrawn. New versions may be added.

[hal-02165756] Chemical Ordering in Bimetallic FeCo Nanoparticles: From a Direct Chemical Synthesis to Application As Efficient High-Frequency Magnetic Material

 (03/03/2021)  
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 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 of the bulk (Ms = 226 Am².kg-1). Composite magnetic materials prepared from these FeCo nanoparticles led to a successful proof-of-concept of integration on inductor-based filters (27% enhancement of the inductance value at 100 MHz).
