Field dependence of dynamic magneto-orientational birefringence in a ferrocolloid based on the nickel-ferrite nanoparticles is examined. The nanoparticles are electrostatically stabilized and suspended in glycerin at low-volume fractions Φ⩽0.75%.

A dynamic probing of magnetic liquids is performed experimentally, using a static magnetic field modulated by another smaller field, normal and alternating. The optical magneto-birefringence under these crossed magnetic fields is recorded as a functi

New ionic ferrofluids containing NiFe2O4 nanoparticles of size ⩽10 nm are investigated. The crystalline structure of the particles is probed by transmission electron microscopy and x-ray scattering. Static magnetization and field-induced birefringe

We investigate the stability of aqueous colloidal dispersions of ionic magnetic nanoparticules as a function of pH. The charge of the γ-Fe2O3 particles is modified, and as a consequence, the interparticle interactions may be tuned through pH variati

Magnetic birefringence experiments under static eld are performed on ionic ferrofluid samples based on Fe2O3 . A colloidal size-sorting of the particles allows to obtain narrow size distributions. The optical birefringence of the solutions is found p

A ‘size sorting’ method performed on ionic magnetic fluids, constituted by polydisperse anionic particles dispersed in water at pH 7 allows ‘monodisperse’ samples to be obtained. Here results on phase transitions observed in these samples wit

The sol–gel transition of thixotropic magnetic gels is studied at macroscopic and mesoscopic scales by rheology and dynamic birefringence. Gelation times are, respectively, determined from small amplitude shear oscillatory measurements in the frame

We show that surface magnetic properties of NiFe2O4 nanoparticles constituting ionic ferrofluids can be investigated in macroscopic experiments. Cross-analysis of static magnetization and field-induced birefringence prove that the particles consist o

Ionic magnetic fluids are aqueous colloidal solutions of magnetic nanoparticles which wear surface charges. Stability of the solution is ensured by screened electrostatic repulsions, and phase transitions “gas-liquid” like are observed when an el
