“…These composites used to be made with iron particles of nano or micro sizes dispersed in a silicon polymer matrix [4][5][6][7]; however, recently other matrices: polymers, polyester, rubbers, thermoplastic elastomers, etc. and particles: ferrites (of barium, cobalt, iron and strontium), alloys of FeAl, and FaGa, etc., are being used [8][9][10][11][12].…”

Magnetic composites of soft magnetic FeGa particles embedded in a silicone matrix have been synthesized. The Villari effect has been studied depending on the size and concentration of the particles and on the magnetic state of the composite. The results indicate a decrease in the Villari effect when the concentration of the magnetic particles increases. These results suggest a relationship between the Villari effect and the mechanical properties of the composites. The Young’s modulus of the composites has been obtained by microindentation and their values related to the intensity and slope of the Villari signals. The results are explained on the basis that the reduction in the cross section of the composite when submitted to stress is the main origin of the variation of the magnetic flux in the Villari effect in this kind of composite. It has also been obtained that the magnetic state of the composite plays an important role in the Villari signal. When the magnetization of the composite is greater, the magnetic flux across the composite is greater too and, so, the same reduction in the cross section originates a greater Villari signal.

“…Such materials have become a growing area of interest due to their promise in magnetic resonance imaging, − biomedical applications, − separations, − and catalysis. − The most common ways to incorporate magnetic properties into polymers have been to blend conventional polymers with strongly magnetic additives (e.g., ferromagnetic inorganic metal oxide or metal nanoparticles, ,,− ,,, magnetic metal-containing ionic liquids (MCILs) ,, ), or to graft or coat polymers onto inorganic magnetic nanopoarticles. − ,− , These materials are appealing due to their ease of preparation and strong magnetic response, but the polymers themselves lack intrinsic magnetic properties. These composites also often have limitations in terms of dispersity control, structural uniformity, and phase-separation. , The design and synthesis of intrinsically magnetic polymers (IMPs, i.e., polymers with magnetic species as part of their structure) offer advantages for structure and composition control.…”
