Platinum tripods as nanometric frequency multiplexing devices
B. C. Camargo, B. Lassagne, R. Arenal +5
Electrical and structural characterization of nano-particles are very important steps to determine their potential applications in microelectronics. In this paper, we adress the cr…
Optimization of the magnetic properties of aligned Co nanowires/polymer composites for the fabrication of permanent magnets
Weiqing Fang, Ioannis Panagiotopoulos, Frédéric Ott +5
We aim at combining high coercivity magnetic nanowires in a polymer matrix in a view to fabricate rare--earth free bonded magnets. In particular, our aim is to fabricate anisotropi…
Numerical calculation of magnetic form factors of complex shape nano-particles coupled with micromagnetic simulations
Fatih Zighem, Frédéric Ott, Thomas Maurer +3
We investigate the calculation of the magnetic form factors of nano-objects with complex geometrical shapes and non homogeneous magnetization distributions. We describe a numerical…
High temperature structural and magnetic properties of cobalt nanowires
Kahina Ait Atmane, Fatih Zighem, Yaghoub Soumare +10
We present in this paper the structural and magnetic properties of high aspect ratio Co nanoparticles (~10) at high temperatures (up to 623 K) using in situ X ray diffraction (XRD)…
Dipolar interactions in magnetic nanowires aggregates
Thomas Maurer, Fatih Zighem, Weiqing Fang +6
We investigate the role of dipolar interactions on the magnetic properties of nanowires aggregates. Micromagnetic simulations show that dipolar interactions between wires are not d…
Exchange bias in Co/CoO core-shell nanowires: Role of the antiferromagnetic superparamagnetic fluctuations
Thomas Maurer, Fatih Zighem, Frederic Ott +6
The magnetic properties of Co (<D>=15 nm, <L>=130nm) nanowires are reported. In oxidized wires, we measure large exchange bias fields of the order of 0.1 T below T ~ 100 K. The ons…
