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…
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/…
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…
