Coherent long-range transfer of angular momentum between magnon Kittel modes by phonons

An K.; Litvinenko A.N.; Kohno R.; Fuad A.A.; Naletov V.V.; Vila L.; Ebels U.; De Loubens G.; Hurdequint H.; Beaulieu N.; Ben Youssef J.; Vukadinovic N.; Bauer G.E.W.; Slavin A.N.; Tiberkevich V.S.; Klein O. (2020)

© 2020 American Physical Society. We report ferromagnetic resonance in the normal configuration of an electrically insulating magnetic bilayer consisting of two yttrium iron garnet (YIG) films epitaxially grown on both ...
Comparative measurements of inverse spin Hall effects and magnetoresistance in YIG/Pt and YIG/Ta

Hahn C.; De Loubens G.; Klein O.; Viret M.; Naletov V.; Ben Youssef J. (2013)

We report on a comparative study of spin Hall related effects and magnetoresistance in YIG|Pt and YIG|Ta bilayers. These combined measurements allow to estimate the characteristic transport parameters of both Pt and Ta ...
Conduction of spin currents through insulating antiferromagnetic oxides

Hahn C.; De Loubens G.; Naletov V.; Ben Youssef J.; Klein O.; Viret M. (2014)

Copyright © EPLA, 2014. Damping processes, associated to magnetization dynamics, allow to generate spin currents from precessing ferromagnets. These can be transmitted into adjacent conducting layers through an interface ...
Detection of microwave spin pumping using the inverse spin hall effect

Hahn C.; De Loubens G.; Viret M.; Klein O.; Naletov V.; Ben Youssef J. (2013)

We report on the electrical detection of the dynamical part of the spin-pumping current emitted during ferromagnetic resonance using inverse spin Hall effect methods. The experiment is performed on a YIG|Pt bilayer. The ...
Direct observation of dynamic modes excited in a magnetic insulator by pure spin current

Demidov V.; Evelt M.; Bessonov V.; Demokritov S.; Prieto J.; Muñoz M.; Ben Youssef J.; Naletov V.; De Loubens G.; Klein O.; Collet M.; Bortolotti P.; Cros V.; Anane A. (2016)

© Thte Author(s) 2016.Excitation of magnetization dynamics by pure spin currents has been recently recognized as an enabling mechanism for spintronics and magnonics, which allows implementation of spin-torque devices based ...
Generation of coherent spin-wave modes in yttrium iron garnet microdiscs by spin-orbit torque

Collet M.; De Milly X.; D'Allivy Kelly O.; Naletov V.; Bernard R.; Bortolotti P.; Ben Youssef J.; Demidov V.; Demokritov S.; Prieto J.; Muñoz M.; Cros V.; Anane A.; De Loubens G.; Klein O. (2016)

In recent years, spin-orbit effects have been widely used to produce and detect spin currents in spintronic devices. The peculiar symmetry of the spin Hall effect allows creation of a spin accumulation at the interface ...
High-efficiency control of spin-wave propagation in ultra-thin yttrium iron garnet by the spin-orbit torque

Evelt M.; Demidov V.; Bessonov V.; Demokritov S.; Prieto J.; Muñoz M.; Ben Youssef J.; Naletov V.; De Loubens G.; Klein O.; Collet M.; Garcia-Hernandez K.; Bortolotti P.; Cros V.; Anane A. (2016)

© 2016 Author(s).We study experimentally with submicrometer spatial resolution the propagation of spin waves in microscopic waveguides based on the nanometer-thick yttrium iron garnet and Pt layers. We demonstrate that by ...
Magnetic resonance spectroscopy of perpendicularly magnetized Permalloy multilayer disks

De Loubens G.; Naletov V.; Viret M.; Klein O.; Hurdequint H.; Ben Youssef J.; Boust F.; Vukadinovic N. (2007)

Using a magnetic resonance force microscope, we compare the ferromagnetic resonance spectra of individual micron size disks with identical diameter, 1 μm, but different layer structures. For a disk composed of a single ...
Mechanical detection of ferromagnetic resonance spectrum in a normally magnetized yttrium-iron-garnet disk

Charbois V.; Naletov V.; Ben Youssef J.; Klein O. (2002)

The ferromagnetic resonance spectrum of a normally magnetized yttrium-iron-garnet disk, with thickness of 4.75 μm and radius of 80 μm, is measured at room temperature both by magnetic resonance force microscopy and by ...
Short-range thermal magnon diffusion in magnetic garnet

An K.; Kohno R.; Thiery N.; Reitz D.; Vila L.; Naletov V.V.; Beaulieu N.; Ben Youssef J.; De Loubens G.; Tserkovnyak Y.; Klein O. (2021)

Using the spin Seebeck effect (SSE), we study the propagation distance of thermally induced spin currents inside a magnetic insulator thin film in the short-range regime. We disambiguate spin currents driven by temperature ...
Temperature Dependence of Magnetic Properties of a Ultrathin Yttrium-Iron Garnet Film Grown by Liquid Phase Epitaxy: Effect of a Pt Overlayer

Beaulieu N.; Kervarec N.; Thiery N.; Klein O.; Naletov V.; Hurdequint H.; De Loubens G.; Ben Youssef J.; Vukadinovic N. (2018)

© 2018 IEEE. Liquid phase epitaxy of an 18 nm thick yttrium-iron garnet (YIG) film is achieved. Its magnetic properties are investigated in the 100-400 K temperature range, as well as the influence of a 3 nm thick Pt ...
