Lithium transport through Lithium-ion battery cathode coatings
Shenzhen Xu, Ryan M. Jacobs, Ha M. Nguyen +4
The surface coating of cathodes using insulator films has proven to be a promising method for high-voltage cathode stabilization in Li-ion batteries. However, there is still substa…
An ac field probe for the magnetic ordering of magnets with random anisotropy
Ha M. Nguyen, Pai-Yi Hsiao
A Monte Carlo simulation is carried out to investigate the magnetic ordering in magnets with random anisotropy (RA). Our results show peculiar similarities to recent experiments th…
Comment on "Critical and slow dynamics in a bulk metallic glass exhibiting strong random magnetic anisotropy" [Appl. Phys. Lett. 92, 011923 (2008)]
Ha M. Nguyen, Pai-Yi Hsiao
In this comment, by using Monte Carlo simulation, we show that the perpendicular shift of hysteresis loops reported in the commented work is nothing special but simply due to the f…
Mangetic phase transition for three-dimensional Heisenberg weak random anisotropy model: Monte Carlo study
Ha M. Nguyen, Pai-Yi Hsiao
Magnetic phase transition (MPT) to magnetic quasi-long-range order (QLRO) phase in a three-dimensional Heisenberg weak (D/J=4) random anisotropy (RA) model is investigated by Monte…
Exchange-driven Collective Behavior in a 3D Array of Nanoparticles
Ha M. Nguyen, Pai-Yi Hsiao
A Monte Carlo simulation is performed in a cubic lattice of interacting identical Stoner-Woldfarth nanoparticles. The model system is a randomly-anisotropic Heisenberg spin system…
Interacting Superparamagnetism in La0.7Sr0.3MnO3 Nanoparticles
Ha M. Nguyen, D. H. Manh, L. V. Hong +2
The magnetic order of La0.7Sr0.3MnO3 nanoparticles (NPs) fabricated in a SPEX D8000 mill was systematically studied. The La0.7Sr0.3MnO3 nanocrystals grow from the milled constituen…
