Study of mechanical and magnetic properties of magnet composite hybrid Fe3O4-NdFeB with matrix polyvinyl alcohol

In the present study material composite magnetite were synthesized by polyvinyl alcohol (PVA) matrix and filler hybrid Fe3O4-NdFeB, for enhancing mechanical magnetic properties. Fe3O4 is obtained from iron sands of East Lombok. The has gained its importance due to low cost, substitute pure BaFe. It’s possible use it as a interest many applications, especially theragnostic agents hyperthermia, drug delivery, resonance imaging. This aims investigate compressive strength, remanent magnetization value (Mr), coercivity (Hc) maximum energy product (BH) max. composition Fe3O4-NdFeB was varied at 10%: 50%, 20%: 40%, 30%:30%, 40%: 20 % total mass (wt) 5 grams. addition, PVA 40% wt. test specimens produced vacum infussion method. results this indicate that addition causes decrease in properties (density, strength), on other hand, an increase (Magnetic remanence coersivity (Hc), (BH)) - NdFeB material, with binding matrices.
