Spin wave propagation and spin polarized electron transport in single crystal iron films
Olga Gladii, David Halley, Yves Henry +1
The technique of propagating spin wave spectroscopy is applied to a 20 nm thick Fe/MgO (001) film. The magnetic parameters extracted from the position of the resonance peaks are ve…
Conductance oscillations in graphene/nanoclusters hybrid material: towards large area single electron devices
Florian Godel, Louis Donald Notemgnou Mouafo, Guillaume Froehlicher +5
Large assemblies of self-organized aluminum nanoclusters embedded in an oxide layer are formed on graphene templates and used to build tunnel-junction devices. Unexpectedly, single…
Optical Writing of Magnetic Properties by Remanent Photostriction
V. Iurchuk, D. Schick, J. Bran +13
We present an optically induced remanent photostriction in BiFeO3, resulting from the photovoltaic effect, which is used to modify the ferromagnetism of Ni film in a hybrid BiFeO3/…
Distance Dependence of the Energy Transfer Rate From a Single Semiconductor Nanostructure to Graphene
François Federspiel, Guillaume Froehlicher, Michel Nasilowski +9
The near-field Coulomb interaction between a nano-emitter and a graphene monolayer results in strong Förster-type resonant energy transfer and subsequent fluorescence quenching. He…
Voltage-controlled inversion of tunnel magnetoresistance in epitaxial Nickel/Graphene/MgO/Cobalt junctions
F. Godel, M. Venkata Kamalakar, B. Doudin +3
We report on the fabrication and characterization of vertical spin-valve structures using a thick epitaxial MgO barrier as spacer layer and a graphene-passivated Ni film as bottom…
Random barrier double-well model for resistive switching in tunnel barriers
Eric Bertin, David Halley, Yves Henry +6
The resistive switching phenomenon in MgO-based tunnel junctions is attributed to the effect of charged defects inside the barrier. The presence of electron traps in the MgO barrie…
Magneto-optical spectroscopy of (Ga,Mn)N epilayers
Stéphane Marcet, David Ferrand, David Halley +7
We report on the magneto-optical spectroscopy and cathodoluminescence of a set of wurtzite (Ga,Mn)N epilayers with a low Mn content, grown by molecular beam epitaxy. The sharpness…
Ordering intermetallic alloys by ion irradiation: a way to tailor magnetic media
H. Bernas, D. Halley, K. -H. Heinig +6
Combining He ion irradiation and thermal mobility below 600K, we both trigger and control the transformation from chemical disorder to order in thin films of an intermetallic ferro…
