W-type hexaferrites nanoparticles are synthesized employing the Co-precipitation method. X-ray powder diffraction (XRD) study reveals polycrystalline nanoparticles having the W-type hexagonal ferrites (HF) structure with the space group P6₃/mmc. Fourier transform infrared spectroscopy (FTIR) show a blue shift in lower frequency and higher frequency bands. UV-Spectra (Ultraviolet visible) show persistent energy band around 450 nm and band gap change of 0.1 eV for substitution. Scanning electron microscopy (SEM) microstructure shows the grains projecting hexagonal faces. The loops of Vibrating sample magnetometer (VSM) explain an appreciable change in magnetic properties and magnetic signature. Screening of antibacterial activity has been performed for the nanosized HFs/PVP (Polyvinylpyrrolidone) hybrid composite against gram positive and gram negative strains of clinical sources.

使用共沉淀法合成W型六价铁氧体纳米粒子。X射线粉末衍射（XRD）研究表明，具有W型六方铁氧体（HF）结构且空间群为P 6 ₃ / mmc的多晶纳米颗粒。傅立叶变换红外光谱（FTIR）在较低频率和较高频带显示蓝移。紫外光谱（可见紫外线）显示了约450 nm的持久能带，取代后的带隙变化为0.1 eV。扫描电子显微镜（SEM）的显微结构显示出六边形突起的晶粒。振动样品磁力计（VSM）的回路说明了磁性能和磁特征的明显变化。纳米级HFs / PVP（聚乙烯吡咯烷酮）杂化复合物已针对革兰氏阳性和革兰氏阴性菌株的临床来源进行了抗菌活性筛选。
