The classical and quantum dynamics of molecular spins on graphene
Klaus Kern, Marko Burghard, Stephan Rauschenbach
Controlling the dynamics of spins on surfaces is pivotal to the design of spintronic(1) and quantum computing(2) devices. Proposed schemes involve the interaction of spins with graphene to enable surface-state spintronics(3,4) and electrical spin manipulat ...
Nature Publishing Group2016Highly Spin-Polarized Carrier Dynamics and Ultra large Photoinduced Magnetization in CH(3)NH(3)Pbl(3) Perovskite Thin Films
Michael Graetzel, Nripan Mathews
Low-temperature solution-processed organic-inorganic halide perovskite CH3NH3PbI3 has demonstrated great potential for photovoltaics and light-emitting devices. Recent discoveries of long ambipolar carrier diffusion lengths and the prediction of the Rashba ...
American Chemical Society2015Nanostripe of subwavelength width as a switchable semitransparent mirror for spin waves in a magnonic crystal
Spin wave transmission experiments are performed on a one-dimensional magnonic crystal (MC) where an injection pad for domain walls reverses the magnetization M of selected nanostripes independently from the otherwise saturated MC. The MC consists of a per ...
2013Propagation of Spin Waves Excited in a Permalloy Film by a Finite-Ground Coplanar Waveguide: A Combined Phase-Sensitive Micro-Focused Brillouin Light Scattering and Micromagnetic Study
The excitation of spin waves by a microwave current injected into a coplanar waveguide with finite-width ground lines on a continuous Permalloy film is investigated both experimentally and numerically. Phase sensitive micro-focused Brillouin light scatteri ...
2013Thermal Spin Transfer Torque and Transverse Spin Relaxation in Spin Valves
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 ...
EPFL2011Current Induced Magnetization Dynamics in Electrodeposited Nanostructures
In this thesis we make use of the Spin Transfer Torque effect from a continuous microwave current to induce and study the spin dynamics of an individual sub-100 nm nanostructure. The idea that an electrical current can carry a spin angular momentum was int ...
EPFL2010Lithography-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 ...
Elsevier2010Spectroscopic Studies on Semiconducting Interfaces with Giant Spin Splitting
The application of an external magnetic field can lift the spin degeneracy of electronic states through its interaction with the electronic magnetic moment. A closely-related phenomenon is the Rashba-Bychkov (RB) effect where symmetry breaking at surfaces ...
EPFL2010Microwave spin-torque excitation in a template-synthesized nanomagnet
Jean-Philippe Ansermet, Elena Murè
A microwave-compatible lithography-free process is shown to allow the electrical contact of a single nanometric spin valve grown by template synthesis. The complex spin dynamics of a single nanomagnet is revealed by resonant microwave current excitations, ...
2009Enhanced magnetic field sensitivity of spin-dependent transport in cluster-assembled metallic nanostructures
Jean-Philippe Ansermet, Jean-Pierre Abid, Santiago Serrano Guisan, Giulia Di Domenicantonio
The emerging field of spintronics explores the many possibilities offered by the prospect of using the spin of the electrons for fast, nanosized electronic devices. The effect of magnetization acting on a current is the essence of giant or tunnel magnetore ...
