We demonstrate in this article that the magnetoelectric (ME) mechanism can be exploited to control the spin current emitted in a spin pumping experiment using moderate electric fields. Spin currents were generated at the interface of a ferromagnet/me

In this work, we study the magnetoelastic behavior of ${\mathrm{Fe}}_{1\ensuremath{-}x}{\mathrm{Ga}}_{x}$ ($0.11lxl0.19$) thin films, grown on glass and oxidized Si(100) amorphous substrates, that present an isotropic crystalline texture in the film

Ferromagnetic thin films with ultra-low damping constants (α) are intensively studied for applications in spintronic devices. We report here the influence of the sputtering conditions (deposition power and temperature) on the magnetic properties of

Laminar heterostructures composed by materials with different ferroic properties have been proposed for the control of magnetism with an applied voltage. We present here a study of the structural and magnetic properties of chemically disordered FePt

In this work we have investigated the influence of Ar sputtering pressure ( P Ar ) in the magnetic properties of polycrystalline sputtered Fe0.89Ga0.11 thin films. The structural characterization shows that the samples are composed by several fiber-l

We have investigated the effects of applying an electric field on the dc and ac magnetic response of Fe 89 Ga 11 thin films ( t = 6 , 11, 17, 22, and 28 nm) that have been deposited on ferroelectric PMN-PT (011) and (001) single crystals. Upon the ap

Standard commercial L-alanine pellets and specially prepared natural lithium formate monohydrate powder samples of specific granulometry were irradiated in a 60Co gamma-ray irradiation plant and in the mixed field (thermal neutrons and gamma photons)

We have observed notable changes in the magnetic response of FePt thin films that we have attributed to a transition in the magnetic domain structure when the film thickness or the temperature is varied. The critical thickness for this transition dep

We present ferromagnetic resonance (FMR) experiments on two low-interacting nanoparticle systems: Fe3O4 and CoFe2O4 corresponding to low- and high-anisotropy cases, respectively. The spectra have been interpreted in terms of a phenomenological model

We have developed a high performance analog electronic device that can be used for the measurement of the inverse spin Hall effect (ISHE) as a function of the applied magnetic field. The electronic circuit is based on the synchronous detection techni
