Coupling between CaWO phonons and Er dopants
Mikhael T. Sayat, Federico Pisani, Hin Lok Chang +8
We investigate the lattice dynamics of CaWO, a promising host crystal for erbium-based quantum memories, using inelastic neutron scattering together with density-functional per…
Phonon density of states of magnetite (\ce{Fe3O4}) nanoparticles via molecular dynamics simulations
Pablo Galaviz, Kyle A. Portwin, Dehong Yu +3
This study presents a comprehensive computational investigation of magnetite nanoparticles, systematically evaluating a range of force fields against experimental results. We analy…
Tuning the Surface States of Nanoparticles for Enhanced Magnetic Anisotropy and Induction Efficacy
Kyle A. Portwin, Pablo Galaviz, Xiaoning Li +9
Magnetite () nanoparticles are crucial for biomedical applications, including magnetic hyperthermia, targeted drug delivery, and MRI contrast enhancement, due to their bio…
Atacamite CuCl(OH) in High Magnetic Fields: Quantum Criticality and Dimensional Reduction of a Sawtooth-Chain Compound
L. Heinze, T. Kotte, R. Rausch +13
We report an extensive high-field study of atacamite CuCl(OH), a material realization of quantum sawtooth chains with weak interchain couplings, in continuous and pulsed ma…
A double-spiral spin ordering in the helimagnet YBaCuFeO
Yu-Hui Liang, Chun-Hao Lai, Chin-Wei Wang +9
Materials with a spiral spin ordering always show a rich phase diagram and can be a playground for studying the exotic physical properties associated with spiral magnetism. Using n…
