Critical Landau velocity in helium nanodroplets

Marcel Drabbels, Evgeniy Loginov, Nils Benedict Brauer, Alberto Hernando de Castro

The best-known property of superfluid helium is the vanishing viscosity that objects experience while moving through the liquid with speeds below the so-called critical Landau velocity. This critical velocity is generally considered a macroscopic property ...

Raman study of the Verwey transition in magnetite at high-pressure and low-temperature: Effect of Al doping

Helmuth Berger

We employed Raman spectroscopy to investigate how the hydrostatic pressure affects the temperature of the Verwey transition in pure (Fe3O4) and Al-doped (Fe2.8Al0.2O4) magnetite. In both samples, pressure suppresses the transition. The Al-doped sample disp ...
