Kinetics of ion migration in the electric field-driven manipulation of magnetic anisotropy of Pt/Co/oxide multilayers
A. Fassatoui, L. Ranno, J. Peña Garcia +4
Magneto-ionics, by which the magnetic properties of a thin layer can be modified through the migration of ions within a liquid or solid electrolyte, is a fast developing research f…
Creation of Magnetic Skyrmion Bubble Lattices by Ultrafast Laser in Ultrathin Films
Soong-Geun Je, Pierre Vallobra, Titiksha Srivastava +10
Magnetic skyrmions are topologically nontrivial spin textures which hold great promise as stable information carriers in spintronic devices at the nanoscale. One of the major chall…
Large voltage tuning of Dzyaloshinskii-Moriya Interaction: a route towards dynamic control of skyrmion chirality
Titiksha Srivastava, Marine Schott, Roméo Juge +14
Electric control of magnetism is a prerequisite for efficient and low power spintronic devices. More specifically, in heavy metal/ ferromagnet/ insulator heterostructures, voltage…
The skyrmion switch: turning magnetic skyrmion bubbles on and off with an electric field
M. Schott, A. Bernand-Mantel, L. Ranno +7
Nanoscale magnetic skyrmions are considered as potential information carriers for future spintronics memory and logic devices. Such applications will require the control of their l…
Mechanisms of exchange bias with multiferroic BiFeO3 epitaxial thin films
H. Bea, M. Bibes, F. Ott +7
We have combined neutron scattering and piezoresponse force microscopy to study the relation between the exchange bias observed in CoFeB/BiFeO3 heterostructures and the multiferroi…
Fractal dimension and size scaling of domains in thin films of multiferroic BiFeO3
G. Catalan, H. Bea, S. Fusil +4
We have analyzed the morphology of ferroelectric domains in very thin films of multiferroic BiFeO3. Unlike the more common stripe domains observed in thicker films BiFeO3 or in oth…
Unravelling the origin of the controversial magnetic properties of BiFeO3 thin films
Helene Bea, Manuel Bibes, Eric Jacquet +3
Single phase (001)-oriented BiFeO3 (BFO) thin films grown by pulsed laser deposition can only be obtained in a narrow window of deposition pressure and temperature and have a low m…
Combining half-metals and multiferroics into epitaxial heterostructures for spintronics
H. Bea, M. Bibes, M. Sirena +8
We report on the growth of epitaxial bilayers of the La2/3Sr1/3MnO3 (LSMO) half-metallic ferromagnet and the BiFeO3 (BFO) multiferroic, on SrTiO3(001) by pulsed laser deposition. T…
Influence of parasitic phases on the properties of BiFeO3 epitaxial thin films
H. Bea, M. Bibes, A. Barthelemy +10
We have explored the influence of deposition pressure and temperature on the growth of BiFeO3 thin films by pulsed laser deposition onto (001)-oriented SrTiO3 substrates. Single-ph…
