Abstract:

In this research, the magnetic and structural properties of Ba0.5 Sr0.5 CuX ZrX Fe12O19 (where x=0-0.8) hexaferrite nanoparticle prepared by sol-gel method have been investigated.[1] The effect of substituted Cu-Zr ions on the magnetic and structural properties of barium strontium hexaferrite have been investigated by FT-IR, XRD, SEM and VSM method. The XRD pattern obtained from the synthesized samples represents that the materials have a single magnetoplumbite phase, and the crystaline size of the particles varies from 42 to 48 nm at X = 0-0.8. That confirms M-type hexagonal crystal structure [2]. Coactivity (Hc) and saturation magnization (Ms) and remanent magnization (Mr) obtained by VSM (Vibrating Sample Magnetometer) technique [3]. The results of the magnetic measurement indicate that coactivity decreases with substation of Cu-Zr from x=0 (5010 Oe) to x=0.8(301.81Oe). But saturation magnization (Ms) don’t follow the trend [4]. The first, Ms of Ba0.5Sr0.5CuX ZrXFe12O19 increased when the value of x increased from 0 to 0.4 mol% and then decreased with the increasing Cu-Zr content [5]. SEM results indicate that the particle morphology is completely hexagonal and that the average particle size increases 90nm to 200 nm with increasing content from x = 0 to x = 0.8 [6]. The magnetic properties show that Cu-Zr substation on the of barium strontium hexaferrite nanoparticle is useful for Electromagnetic wave absorber.
