Thermal Spin Transfer Torque and Transverse Spin Relaxation in Spin Valves

Haiming Yu

Spin caloritronics, i.e., the addition of thermal effects to the electrical and magnetic properties of nanostructures, has recently seen a rapid development. It has been predicted that a heat current can exert a spin torque on the magnetization in a nanost ...

Augmented White Cane with Multimodal Haptic Feedback

Hannes Bleuler, Roger Gassert, Dominique Chapuis, Simon Gallo, Laura Santos Carreras

This paper proposes an instrumented handle with multimodal augmented haptic feedback, which can be integrated into a conventional white cane to extend the haptic exploration range of visually impaired users. The information extracted from the environment t ...

On the upper part load vortex rope in Francis turbine: Experimental investigation

François Avellan, Christophe Nicolet, Pierre Maruzewski, Amirreza Zobeiri

The swirling flow developing in Francis turbine draft tube under part load operation leads to pressure fluctuations usually in the range of 0.2 to 0.4 times the runner rotational frequency resulting from the so-called vortex breakdown. For low cavitation n ...

Lithography-free study of spin torque

Jean-Philippe Ansermet, Elena Murè

We developed a non-lithographic technique to contact sub-100 nm nanowires for spin transfer torque experiments. Co/Cu multilayers were grown by electrodeposition in nanoporous commercial polycarbonate membranes from a Co/Cu bath. A home-made sample holder ...

Torque anomalies at magnetization plateaux in quantum magnets with Dzyaloshinskii-Moriya interactions

Frédéric Mila

We investigate the effect of Dzyaloshinskii-Moriya (DM) interactions on torque measurements of quantum magnets with magnetization plateaux in the context of a frustrated spin-1/2 ladder. Using extensive DMRG simulations, we show that the DM contribution to ...

Double-resonant x-ray and microwave absorption: Atomic spectroscopy of precessional orbital and spin dynamics

Giovanni Boero, Stefano Rusponi, Pietro Gambardella

We show that double-resonance spectra recorded during the simultaneous absorption of x-ray and microwave (MW) photons are a fingerprint of the perturbed electronic configuration of atomic species driven to ferromagnetic resonance. X-ray absorption measurem ...

Numerical Flow Analysis in a Pelton Turbine Bucket

François Avellan, Mohamed Farhat, Alexandre Perrig

The flow in the Pelton turbine bucket is three-dimensional, unsteady, turbulent, features a free surface, and is influenced by the rotation-induced forces. It is therefore difficult to investigate how the energy transfer takes place between the water flow ...
