Ferromagnetism of Molecular Beam Epitaxy‐grown Ultra‐thin Cr2Ge2Te6 Films Down to the Monolayer Limit on Si Substrates

open access: yesAdvanced Materials, EarlyView.
Uniform monolayer Cr2Ge2Te6 films are achieved on Si substrates by molecular beam epitaxy. Intrinsic ferromagnetism with perpendicular magnetic anisotropy is established in the films by anomalous Hall effect and superconducting quantum interference device measurements, albeit with strong magnetic fluctuations characteristic of its 2D nature.

Drag force on bubbles in bubble swarms

open access: yes, 2010
Direct Numerical Simulations with a Front Tracking model have been used to study the hydrodynamic behavior of bubble swarms for the air/water system. In this work, we focus on the effect of the presence of neighboring bubbles on the drag as a function of the void fraction, especially at higher void fractions.

A method for estimating sound speed and the void fraction of bubbles from sub-bottom sonar images of gassy seabeds

open access: yes, 2007
There is increasing interest in the effect of bubbles in gassy sediment. This is, first, because ofthe impact those bubbles have on the structural integrity and load-bearing capabilities of thesediment; second, because the presence of bubbles can be ...
