Magnetic Properties of Poly (Divinylbenzene, Ethylene Glycol Dimethacrylate and Vinyl Alcohol) Containing Barium Ferrite Nanoparticles

Abstract

Three dierent kinds of polymer lms, poly (divinylbenzene), poly (ethylene glycol dimethacrylate) and poly (vinyl alcohol), containing M -type hexagonal barium ferrites (BaFe12O19) were synthesized on glass substrates by using surface polymerization method. The structural properties were characterized by X-ray diraction and atomic force microscopy. X-ray diraction patterns show that polymer lms have a polycrystalline structure. The magnetic measurement of polymer lms were examined at room temperature using vibrating sample magnetometer and magnetic force microscopy, respectively. The magnetic measurements indicate that P(VA)-BF lms exhibit higher saturation magnetization and coercive eld than P(EGDMA)-BF and P(DVB)-BF lms.

ELECTRON SPIN RESONANCE RESPONSE OF BaFe12O19 NANOPARTICLE EMBEDDED POLYDIVINYLBENZENE MAGNETIC FILM

“…Materials used in this investigation are divinylbenzene (DVB), barium ferrite (97% trace metal basis, particle size <100 nm) nano particles and toluene which are supplied from Aldrich Chemical Company (USA). The preparation procedure of the poly [DVB/ BaFe12O19] magnetic film has been given our previous work [13]. Here, we summarized the steps.…”

Structural Design and Characterization of BaMgxCo2-xFe16O27Hexaferrites Based on ab initio Computations

“…With the arrival of modern electronic, microwave and magnetic devices, the electromagnetic interference has become a critical problem [2]. It is therefore important to design materials that can attenuate electromagnetic radiations.…”
