High-frequency giant magnetoresistance measurement to study the dynamics of a micron-scale spin-valve sensor

We report on the study of the magnetization dynamic of a single micrometric spin-valve element. by high-frequency giant magnetoresistance measurement. We have combined transport measurements in the microwave range and large band ferromagnetic resonance wit ...

Second-harmonic response and temperature differential resistivity of noncollinear spin valves

Jean-Philippe Ansermet, Julie Dubois

By means of a diffusive description of spin-dependent thermal and electrical transport using Pauli-spin matrices, we analyze the spin-dependent transport mechanisms that determine the voltage response of a metallic spin valve to an ac temperature oscillati ...

Magnetic correlations at graphene edges: Basis for novel spintronics devices

Oleg Yazyev

Magnetic zigzag edges of graphene are considered as a basis for novel spintronics devices despite the fact that no true long-range magnetic order is possible in one dimension. We study the transverse and longitudinal fluctuations of magnetic moments at zig ...

In-Situ vs. Ex-Situ Nanocrystallization of Mn-Doped ZnO

László Forró, Arnaud Magrez, Duncan Thomas Lindsay Alexander, Zlatko Mickovic

Following the current interest in transition metal doped dielectrics for spintronic applications, Mn-doped ZnO is being made by thermal decomposition of Mn-doped hydrozincite,  (MnxZn1–x)5(OH)6–2n (CO3)1+n, precursors that have been prepared by a novel syn ...

Spin-orbit split two-dimensional electron gas with tunable Rashba and Fermi energy

Klaus Kern, Marco Grioni, Luca Moreschini, Daniela Pacilè

We demonstrate that it is possible to tune the Rashba energy, introduced by a strong spin-orbit splitting, and the Fermi energy in a two-dimensional electron gas by a controlled change of stoichiometry in an artificial surface alloy. In the BixPb1-x/Ag(111 ...

Weak-and strong-coupling limits of the two-dimensional Frohlich polaron with spin-orbit Rashba interaction

Claudio Grimaldi

The continuous progress in fabricating low-dimensional systems with large spin-orbit couplings has reached a point in which nowadays materials may display spin-orbit splitting energies ranging from a few to hundreds of meV. This situation calls for a bette ...

Energy levels of a two-dimensional hydrogen atom with spin-orbit Rashba interaction

Claudio Grimaldi

Electronic bound states around charged impurities in two-dimensional systems with structural inversion asymmetry can be described in terms of a two-dimensional hydrogen atom in the presence of a Rashba spin-orbit interaction. Here, the energy levels of the ...

Single-chip detector for electron spin resonance spectroscopy

Giovanni Boero

We have realized an innovative integrated detector for electron spin resonance spectroscopy. The microsystem, consisting of an LC oscillator, a mixer, and a frequency division module, is integrated onto a single silicon chip using a conventional complement ...

Template Nanowires for Spintronics Applications: Nanomagnet Microwave Resonators Functioning in Zero Applied Magnetic Field

Jean-Philippe Ansermet, Oleg Yazyev

Low-cost spintronic devices functioning in zero applied magnetic field are required for bringing the idea of spin-based electronics into the real-world industrial applications. Here we present first microwave measurements performed on nanomagnet devices fa ...

Influence of antiferromagnetic spin ordering on the far-infrared active optical phonon modes of alpha-MnSe

The effects of spin-phonon interaction and magnetic anisotropy on the temperature dependence of the infrared optical phonon modes in the antiferromagnetic alpha-MnSe are investigated by use of Green’s function formalism within 1/z perturbation framework. T ...
