Modeling Molecular Magnets with Large Exchange and On-Site Anisotropies
Sumit Haldar, Rajamani Raghunathan, Jean-Pascal Sutter +1
Spins in molecular magnets can experience both anisotropic exchange interactions and on-site magnetic anisotropy. In this paper we study the effect of exchange anisotropy on the mo…
Magnetic anisotropy determination and magnetic hyperthermia properties of small Fe nanoparticles in the superparamagnetic regime
B. Mehdaoui, A. Meffre, L. -M. Lacroix +5
We report on the magnetic and hyperthermia properties of iron nanoparticles synthesized by organometallic chemistry. They are 5.5 nm in diameter and display a saturation magnetizat…
Large specific absorption rates in the magnetic hyperthermia properties of metallic iron nanocubes
B. Mehdaoui, A. Meffre, L. -M. Lacroix +5
We report on the magnetic hyperthermia properties of chemically synthesized ferromagnetic 11 and 16 nm Fe(0) nanoparticles of cubic shape displaying the saturation magnetization of…
Magnetic hyperthermia in single-domain monodisperse FeCo nanoparticles: Evidences for Stoner-Wohlfarth behaviour and large losses
L. -M. Lacroix, R. Bel Malaki, J. Carrey +4
We report on hyperthermia measurements on a colloidal solution of 15 nm monodisperse FeCo nanoparticles (NPs). Losses as a function of the magnetic field display a sharp increase f…
Tailoring the Magnetic Anisotropy in CoRh Nanoalloys: Experiment and Theory
M. Muñoz-Navia, J. Dorantes-Dávila, D. Zitoun +5
The magnetic moments and magnetic anisotropy energy (MAE) of CoRh alloy nanoparticles are determined experimentally and theoretically. Non-trivial correlations between chemical ord…
Magnetoresistance and collective Coulomb blockade in super-lattices of ferromagnetic CoFe nanoparticles
R. P. Tan, J. Carrey, C. Desvaux +4
We report on transport properties of millimetric super-lattices of CoFe nanoparticles surrounded by organic ligands. R(T)s follow R(T) = R_0.exp(T/T_0)^0.5 with T_0 ranging from 13…
