Analytical description for current-induced vortex core displacement

In this article, an analytical model for current-induced vortex core displacement is developed. By using this model, one can solve the equations of motion analytically to determine the effects of the adiabatic and nonadiabatic spin-torque terms. The final ...

Current-induced domain wall motion in nanoscale ferromagnetic elements

We review the details of domain wall (DW) propagation due to spin-polarized currents that could potentially be used in magnetic data storage devices based on domains and DWs. We discuss briefly the basics of the underlying spin torque effect and show how t ...

Phase Field Modelling Of Twinned Dendrite Growth

Michel Rappaz, Jean-Luc Desbiolles, Mario Alberto Salgado Ordorica

Twinned dendrite growth has been found to occur in aluminum alloys when critical thermal conditions (G approximate to 100 K/cm, nu(s) approximate to 1 mm/s) and a slight convection in the melt are present during directional solidification. Split in their t ...

Characterization and modeling of twinned dendrite growth

Mario Alberto Salgado Ordorica

The formation of feathery grains during semi-continuous casting of Al-alloys [1, 2] is an interesting problem from both practical and theoretical points of view. These structures are formed by a lamellar sequence of twinned and untwinned regions separated ...

Design and Control of an Innovative Micro-Rover

Roland Siegwart, Michel Lauria

During recent years the European Space Agency (ESA) has started to develop concepts for micro-rovers for planetary missions. An ESA Technology Research Program (TRP) activity "Micro-Robots for Scientific Applications" has been dedicated to this subject. Wi ...
