Exploring possible magnetic monopoles-induced magneto-electricity in spin ices

Autor: Alexanian, Y., Saugnier, J., Decorse, C., Robert, J., Ballou, R., Lhotel, E., Debray, J., Gay, F., Simonet, V., de Brion, S.

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 devices where their cross-manipulation by external parameters such as

Terahertz Magneto-optical investigation of quadrupolar spin-lattice effects in magnetically frustrated Tb2Ti2O7

Autor: Amelin, K., Alexanian, Y., Nagel, U., Room, T., Robert, J., Debray, J., Simonet, V., Decorse, C., Wang, Z., Ballou, R., Constable, E., de Brion, S.

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 vibronic coupling, which occurs between the Tb3+ electronic levels and

Microscale crystalline rare-earth doped resonators for strain-coupled optomechanics

Autor: Motte, J. F., Galland, N., Debray, J., Ferrier, A., Goldner, P., Lučić, N., Zhang, S., Fang, B., Coq, Y. Le, Seidelin, S.

Publikováno v: Journal of Modern Physics 10, 1342-1352 (2019)

Rare-earth ion doped crystals for hybrid quantum technologies is an area of growing interest in the solid-state physics community. We have earlier theoretically proposed a hybrid scheme of a mechanical resonator which is fabricated out of a rare-eart

Cadmium arsenide (Cd3As2) has recently became conspicuous in solid-state physics due to several reports proposing that it hosts a pair of symmetry-protected 3D Dirac cones. Despite vast investigations, a solid experimental insight into the band struc

Magnetic and dielectric order in the kagome-like francisite Cu$_3$Bi(SeO$_3$)$_2$O$_2$Cl

Autor: Constable, E., Raymond, S., Petit, S., Ressouche, E., Bourdarot, F., Debray, J., Josse, M., Fabelo, O., Berger, H., deBrion, S., Simonet, V.

Publikováno v: Phys. Rev. B 96, 014413 (2017)

We report a single-crystal neutron diffraction and inelastic neutron scattering study on the spin 1/2 cuprate Cu$_3$Bi(SeO$_3$)$_2$O$_2$Cl, complemented by dielectric and electric polarization measurements. The study clarifies a number of open issues
