In the context of the study of the interplay between magnetism and superconductivity, a phase transition has been evidenced as a function of magnetic field between two phases having identical magnetic symmetry. Since this effect cannot be magnetically driven, it implies a modification of the nature ... More »

Legend: Q-constant energy scans (solid symbols), at two Bragg positions shown in the inset, fitted by a series of Gaussian functions (solid lines). This figure emphasizes one series of transverse modes when the scattering vector Q is parallel to the direction of the ordered antiferromagnetic ... More »

The compound URu2Si2 is the object of intense investigations for twenty years because the nature of the phase transition observed at T0 = 17.5 K in this compound still remains a mystery despite an impressive experimental effort. Our polarized neutron diffraction measurements suggest that the ... More »

This result is on the front page of Phys. Rev Lett. 107 (13). The article by S. Raymond et al., Understanding the Complex Phase Diagram of Uranium: The Role of Electron-Phonon Coupling, reports on an experimental study coupled to theoretical calculations explaining the phase diagram of uranium, for ...
