Characterization and magnetic properties of Sm-and Gd-substituted CoFe2O4 nanoparticles prepared by forced hydrolysis in polyol
L. Ben Tahar,Leila Samia Smiri,Mathieu Artus,A.-L. Joudrier,F. Herbst,Marie-Joseph Vaulay,Souad Ammar,Fernand Fiévet +7 more
TL;DR: In this article, the insertion of Sm{sup 3+} and Gd{sup 4+} cations into the cobalt ferrite structure has been investigated and X-ray micro-analysis (EDX) shows that the RE contents are close to the nominal ones.

Size-dependent magnetic properties of CoFe2O4 nanoparticles prepared in polyol
Mathieu Artus,Lotfi Ben Tahar,Frédéric Herbst,Leila Samia Smiri,Françoise Villain,Nader Yaacoub,Jean-Marc Greneche,Souad Ammar,Fernand Fiévet +8 more
TL;DR: In this article, high crystalline CoFe2O4 nanoparticles with different diameters ranging from 2.4 to 6.1 nm have been synthesized by forced hydrolysis in polyol.

Synthesis and Magnetic Properties of Ferrimagnetic CoFe2O4 Nanoparticles Embedded in an Antiferromagnetic NiO Matrix
Mathieu Artus,Souad Ammar,L. Sicard,Jean-Yves Piquemal,F. Herbst,Marie-Joseph Vaulay,Fernand Fiévet,Vincent Richard +7 more
TL;DR: In this paper, the same authors used a ferrimagnetic CoFe2O4 core embedded in well-crystallized antiferromagnetic NiO. Magnetic properties such as coercivity, hysteresis loop shift, and blocking temperature were analyzed regarding exchange bias features by comparing the magnetic data measured on these particles to those obtained on fresh CoFe 2O4 particles mechanically dispersed in a diamagnetic Al2O3 matrix.

On the microstructural and magnetic properties of fine-grained CoFe2O4 ceramics produced by combining polyol process and spark plasma sintering
Thomas Gaudisson,Mathieu Artus,Ulises Acevedo,Frédéric Herbst,Sophie Nowak,Raul Valenzuela,Souad Ammar +6 more
TL;DR: In this article, high-density fine-grained ceramics were produced using Spark Plasma Sintering technique at 600 and 500°C, under vacuum and applying a uniaxial pressure of more than 80 MPa.

Magnetic properties of CoFe1.9RE0.1O4 nanoparticles (RE=La, Ce, Nd, Sm, Eu, Gd, Tb, Ho) prepared in polyol
L. Ben Tahar,Mathieu Artus,Souad Ammar,Leila Samia Smiri,Frédéric Herbst,M.-J. Vaulay,V. Richard,Jean-Marc Greneche,F. Villain,Fernand Fiévet +9 more
TL;DR: In this paper, the effect of substitution of RE 3+ ions for Fe 3+ ones on the structure, the microstructure, the chemical homogeneity, and the magnetic properties of the cobalt ferrite system was investigated.
