A TEM study of morphological and structural degradation phenomena in LiFePO4-CB cathodes
Duc-The Ngo, Roberto Scipioni, Søren Bredmose Simonsen +2
LiFePO4-based cathodes suffer from various degradation mechanisms which influences the battery performance. In this paper morphological and structural degradation phenomena in labo…
Simple top-down preparation of magnetic BiGdFeTiO nanoparticles by ultrasonication of multiferroic bulk material
M. A. Basith, D. -T. Ngo, A. Quader +5
We present a simple technique to synthesize ultrafine nanoparticles directly from bulk multiferroic perovskite powder. The starting materials, which were ceramic pellets of the nom…
Tunable exchange bias effect in magnetic BiGdFeTiO nanoparticles at temperatures up to 250 K
M. A. Basith, F. A. Khan, Bashir Ahmmad +5
The exchange bias (EB) effect has been observed in magnetic BiGdFeTiO nanoparticles. The influence of magnetic field cooling on the exchange bia…
Perpendicular magnetic anisotropy and magnetization process in CoFeB/Pd multilayer films
Duc-The Ngo, Duy-Truong Quach, Quang-Hung Tran +3
Perpendicular magnetic anisotropy (PMA) and dynamic magnetization reversal process in [CoFeB nm/Pd 1.0 nm] ( = 0.4, 0.6, 0.8, 1.0, and 1.2 nm; = 2 - 20) multilayer f…
Domain wall motions in perpendicularly magnetized CoFe/Pd multilayer nanowire
Zhaoliang Meng, Manoj Kumar, Jinjun Qiu +3
Current induced domain wall (DW) motion has been investigated in a 600-nm wide nanowire using multilayer film with a structure of Ta(5 nm)/Pd(5 nm)/[CoFe(0.4 nm)/Pd(1.2 nm)]…
Interfacial tuning of perpendicular magnetic anisotropy and spin magnetic moment in CoFe/Pd multilayers
Duc-The Ngo, Z. L. Meng, T. Tahmasebi +6
We report on a strong perpendicular magnetic anisotropy in [CoFe 0.4nm/Pd t]6 (t = 1.0-2.0 nm) multilayers fabricated by DC sputtering in a ultrahigh vacuum chamber. Saturation mag…
Modulation of domain wall dynamics in TbFeCo single layer nanowire
Duc-The Ngo, Kotaro Ikeda, Hiroyuki Awano
We demonstrate the possibility to write and modulate the magnetic domain walls in a TbFeCo single layer nanowire (300 nm width, 150 m length). To realize this, a tiny magnetic d…
CoB/Ni-Based Multilayer Nanowire with High-Speed Domain Wall Motion under Low Current Control
Duc-The Ngo, Norihito Watanabe, Hiroyuki Awano
The spin-transfer torque motion of magnetic domain walls (DWs) in a CoB/Ni-based nanowire driven by a low current density of (1.12\pm0.8)\times10^{11} A m^{-2} has been observed in…
Synthesis and structural characterization of uranium-doped Ca2CuO3, a 1D quantum antiferromagnet
Nam Nhat Hoang, Dang Chinh Huynh, Duc Tho Nguyen +4
The technological settings of a modified sol-gel method for preparation of highly fine homogeneous powder Ca2CuO3 doped with uranium 238 (x=0-0.05) is presented. The analysis of st…
