Direct identification of local doping effects in Barium-hexaferrite by electron vortex beams
Darius Pohl, Hitoshi Makino, Arthur Ernst +4
We demonstrate atomic-scale mapping of local magnetic moments and doping effects in Ti-doped barium hexaferrite (BaFe11TiO19) using atom-sized electron vortex beams (EVBs) with con…

Mode-Dependent Phonon Relaxation in fcc Ni: Insights from Molecular Dynamics Simulations with Frozen-Trajectory Excitations
Wojciech Marciniak, Joanna Marciniak, José Ãngel Castellanos-Reyes +1
We present a computational method and apply it to study phonon relaxation in face-centered cubic (fcc) nickel (Ni). The phonons are excited beyond their thermal equilibrium populat…
