Pt cap** effects on the perpendicular magnetic properties of Pt/Co2MnSi/MgAl2O4 trilayers
A series of Pt/Co2MnSi(CMS)/MgAl2O4(MAO) trilayers are fabricated by sputtering. Perpendicular magnetic anisotropy (PMA) is observed to build in the Pt/CMS/MAO trilayers annealed at 200 °C with a relatively narro...

Ultrafast transient photoinduced absorption in Ge core and Ge/GeO2 core/shell nanoparticles: effect of interface passivation
Transient photoinduced absorption in Ge core and Ge/GeO2 core/shell nanoparticles (NPs) has been studied in visible spectral range. Two distinctive relaxation processes were observed: the fast relaxation with lif...
