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.

Berenice Cruz-Franco,Thomas Gaudisson,Souad Ammar,Ana María Bolarín-Miró,Félix Sánchez De Jesús,Frederic Mazaleyrat,Sophie Nowak,Gabriela Vázquez-Victorio,R. Ortega-Zempoalteca,Raul Valenzuela +9 more
TL;DR: In this paper, a review of the magnetic properties of spinel ferrite NPs (Ni-Zn, Co, and magnetite) synthesized by the polyol method, in different degrees of aggregation, from monodisperse NPs, to clusters formed by tens to hundreds of NPs.

On the exact crystal structure of exchange-biased Fe3O4–CoO nanoaggregates produced by seed-mediated growth in polyol
Thomas Gaudisson,R. Sayed-Hassan,R. Sayed-Hassan,Nader Yaacoub,Giulia Franceschin,Sophie Nowak,Jean-Marc Greneche,Nicolas Menguy,Ph. Sainctavit,Souad Ammar +9 more
TL;DR: In this article, the nucleation and growth mechanism of exchange-biased magnetically contrasted highly crystallized and perfectly epitaxied Fe3O4-CoO nanoaggregates were investigated using local probe analysis, namely 57Fe Mossbauer and L2,3 Co XMCD spectroscopies, and advanced magnetometry.

Severe reduction of Ni-Zn ferrites during consolidation by Spark Plasma Sintering (SPS)
TL;DR: In this article, Zn ferrites of composition Zn 0.7 Ni 0.3 Fe 2 O 4 were synthesized by the polyol method and subsequently consolidated into fine grain, high density ceramics by means of Spark Plasma Sintering at 600°C for 10min, under vacuum and applying a uniaxial pressure of 80MPa.

Exchange‐Biased Fe3−xO4‐CoO Granular Composites of Different Morphologies Prepared by Seed‐Mediated Growth in Polyol: From Core–Shell to Multicore Embedded Structures
Giulia Franceschin,Thomas Gaudisson,Nicolas Menguy,B. C. Dodrill,Nader Yaacoub,Jean-Marc Greneche,Raul Valenzuela,Raul Valenzuela,Souad Ammar +8 more
TL;DR: In this paper, a magnetically contrasted granular hetero-nanostructures are prepared by seed-mediated growth in polyol, properly combining two oxide phases with different magnetic order, ferrimagnetic (F) partially oxidized magnetite Fe3−xO4 and antiferromagnetic (AF) cobalt oxide.
