Title: Structural Characterization of Magnetic Nano-particles Suspensions, Using Magnetic Measurements
Author: Popa N.-C.; Siblini A.; Rousseau J.-J.; Blanc-Mignon M.-F.; CHATELON, Jean Pierre
Abstract: P curves, Magnetic fluids, Ferrofluids, Nanostructural characterization, Magnetic powders, Hysteresis curve, Magnetic nanocomposite materialsThe paper describes some characteristics of the “P” curves for structural characterization of magnetic nano-particles suspensions (complex fluids, complex powders, complex composite materials, or living biological materials having magnetic properties). In the case of these materials, the magnetic properties are conferred to various carrier liquids by artificially integrating in their structure ferromagnetic particles of different sizes. The magnetic properties are usually shown by the hysteresis curve. The structure can be seen on (electronic) micrography. The P curves offer another possibility to determine the structure of the magnetic component of a complex fluid by numerical analysis of the magnetization curve experimentally obtained. The paper presents a detailed approach of the P curves and some limitations in their use.
