Field-induced double spin spiral in a frustrated chiral magnet
M. Ramakrishnan, E. Constable, A. Cano +14
We report the direct observation of a magnetic-feld induced long-wavelength spin spiral modulation in the chiral compound Ba3TaFe3Si2O14. This new spin texture emerges out of a chi…
Iron-based superconductors: Foreword
Henri Alloul, Andres Cano
We introduce the thematic (open access) issue published in Comptes Rendus Physique. This issue is focused on the so-called Fe-based superconductors that, since the discovery of sup…
Helical bunching and symmetry lowering inducing multiferroicity in Fe langasites
Laura Chaix, Rafik Ballou, Andres Cano +12
The chiral Fe-based langasites represent model systems of triangle-based frustrated magnets with a strong potential for multiferroicity. We report neutron scattering measurements f…
Helical order and multiferroicity in the quasi-kagome system KCuAsO(OD)
Gøran J. Nilsen, Yoshihiko Okamoto, Hajime Ishikawa +7
Several Cu hydroxide minerals have recently been identified as candidate realizations of the kagome Heisenberg model. In this context, we have studied the distorted…
Magneto- to electro-active transmutation of spin waves in ErMnO3
Laura Chaix, Sophie De Brion, Sylvain Petit +10
The low energy dynamical properties of the multiferroic hexagonal perovskite ErMnO3 have been studied by inelastic neutron scattering as well as terahertz and far infrared spectros…
THz Magneto-electric atomic rotations in the chiral compound BaNbFeSiO
Laura Chaix, Sophie De Brion, Florence Levy-Bertrand +9
We have determined the terahertz spectrum of the chiral langasite BaNbFeSiO by means of synchrotron-radiation measurements. Two excitations are revealed that are…
Anisotropic conductance at improper ferroelectric domain walls
Dennis Meier, Jan Seidel, Andres Cano +6
Transition metal oxides hold great potential for the development of new device paradigms because of the field-tunable functionalities driven by their strong electronic correlations…
Pseudo-proper ferroelectricity in thin films
A. Cano, A. P. Levanyuk
We study ferroelectricity in thin films of pseudo-proper ferroelectrics such as the so-called spiral multiferroics. We find that this type of ferroelectricity stands better against…
