Exploring possible magnetic monopoles-induced magneto-electricity in spin ices
Y. Alexanian, J. Saugnier, C. Decorse +7
The possibilities of combining several degrees of freedom inside a unique material have recently been highlighted in their dynamics and proposed as information carriers in quantum…
Lattice dynamics and spin excitations in the metal-organic framework [CHNH][Co(HCOO)]
Lei Ding, Claire V. Colin, Virginie Simonet +11
In metal-organic-framework (MOF) perovskites, both magnetic and ferroelectric orderings can be readily realized by compounding spin and charge degrees of freedom. The hydrogen bond…
Collective magnetic state induced by charge disorder in the non-Kramers rare-earth pyrochlore TbScNbO
Y. Alexanian, E. Lhotel, R. Ballou +15
Geometrical frustration, as in pyrochlore lattices made of corner-sharing tetrahedra, precludes the onset of conventional magnetic ordering, enabling the stabilization of fluctuati…
Vibronic collapse of ordered quadrupolar ice in the pyrochore magnet TbTiO
Yann Alexanian, Julien Robert, Virginie Simonet +8
While the spin liquid state in the frustrated pyrochlore TbTiO has been studied both experimentally and theoretically for more than two decades, no definite…
Terahertz Magneto-optical investigation of quadrupolar spin-lattice effects in magnetically frustrated Tb2Ti2O7
K. Amelin, Y. Alexanian, U. Nagel +9
The significance of spin-lattice coupling in the phase diagram of the quantum spin-icepyrochlore Tb2Ti2O7 has been a topic of debate for some time. Here, we focus on the aspect of…

In the spinel compound GeCoO, the Co pyrochlore sublattice presents remarkable magnetic field-induced behaviors that we unveil through neutron and X-ray single-cryst…
Phonons in the multiferroic langasite BaNbFeSiO : evidences for symmetry breaking
C Toulouse, M Cazayous, S De Brion +7
The chiral langasite BaNbFeSiO is a multiferroic compound. While its magnetic order below T=27 K is now well characterised, its polar order is still con…
Helical bunching and symmetry lowering inducing multiferroicity in Fe langasites

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…
Lattice and spin excitations in multiferroic h-YMnO3

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…
Shifted loops and coercivity from field imprinted high energy barriers in ferritin and ferrihydrite nanoparticles
N. J. O. Silva, V. S. Amaral, A. Urtizberea +8
We show that the coercive field in ferritin and ferrihydrite depends on the maximum magnetic field in a hysteresis loop and that coercivity and loop shifts depend both on the maxim…
