Magnetic resonance of ferrite nanoparticles:: evidence of surface effects
Florence Gazeau,Jean-Claude Bacri,Francois Gendron,Régine Perzynski,Yu. L. Raikher,V. I. Stepanov,Emmanuelle Dubois +6 more
TL;DR: In this article, the orientation of particles inside the fluid is employed to monitor the orientational distribution of the anisotropy axes by solidifying the MF matrix under the external field.

Magnetic colloidal properties of ionic ferrofluids
TL;DR: In this paper, the magnetic properties of colloidal suspensions of γ-Fe 2 O 3 particles, obtained through a chemical synthesis, are investigated using an optical technique, and it is verified that these ionic aqueous ferrofluids are stable in high fields.

Phase diagram of an ionic magnetic colloid: Experimental study of the effect of ionic strength
TL;DR: In this article, the phase separation in zero magnetic field of an ionic ferrofluid is experimentally studied as a function of the ionic strength of the solution, and a reduced phase diagram is built up.

Electrostatic co-assembly of iron oxide nanoparticles and polymers : towards the generation of highly persistent superparamagnetic nanorods
TL;DR: In this paper, anionically coated iron oxide nanocrytals (superparamagnetic, size 7 nm) and cationic-neutral block copolymers were used to fabricate rod-like nanodevices.
