  • CoNiP/Au Multisegment Magnetic Nanowires: Synthesis and Aminothiophenol (4-ATP) Functionalization

    • Authors: Do, Quang Ngoc; Hoang, Thi Nu; Luu, Van Thiem; Luu, Manh Quynh; Le, Tuan Tu (2017)

  • The magnetic properties in CoNiP/Au multisegments nanowire were investigated. All the samples were prepared by electrodeposition method with pH of 5.5 and room temperature. The electrochemical potential of CoNiP was determined by cycle voltammetary. The crystalline structure and morphology of the samples were characterized by X-ray diffraction (XRD), Scanning Electron Miroscopy (SEM) and High-resolution transmission electron microscopy (HRTEM), respectively. The hysteresis loops were measured at room temperature using vibrating sample magnetometry (VSM). The SEM and TEM image showed that the CoNiP/Au nanowires with diameters about 50 nm. The lattice spacing of the CoNiP samples were ...

  • Influences of pH Values on Magnetic CoNiP Nanowires Fabrication

    • Authors: Luu, Van Thiem; Le, Tuan Tu; Pham, Duc Thang (2014)

  • CoNiP nanowire arrays were fabricated by electrodeposition method into polycarbonate (PC) templates at different pH values. It is obvious that the crystal structure of the CoNiP nanowires depends on the pH values of electrolyte. The XRD results show that crystal structure of the CoNiP nanowires is hcp structure and the intensity of the hcp (002) increased enhances as solution pH=3.5. Magnetic measurements indicate that CoNiP nanowires show a transition from soft to hard magnetic properties with pH values from 2.0 to 3.5 and the maximum coercivity is 1630 Oe.
