Collective magnetic excitations in mixed-valence Sm0.83Y0.17S
P. A. Alekseev, J. -M. Mignot, A. Ochiai +6
The magnetic spectral response of black-phase mixed-valence Sm0.83Y0.17S has been measured by inelastic neutron scattering on a single crystal. Two magnetic peaks are observed in t…
Antiferroquadrupolar Order in the Magnetic Semiconductor TmTe
J. M. Mignot, A. Gukasov, C. P. Yang +3
The physical properties of the antiferroquadrupolar state occurring in TmTe below TQ=1.8 K have been studied using neutron diffraction in applied magnetic fields. A field-induced a…
Single crystal structural study of the charge ordered phase of Pr0.6Ca0.4MnO3: electronic localization beyond the atomic level
A. Daoud-Aladine, J. Rodriguez-Carvajal, L. Pinsard-Gaudart +2
In the R1/2D1/2MnO3 manganites (R: rare earth, D: divalent cation), the structural phase transition at Tco is commonly interpreted as a concomitant charge and orbital ordering (CO/…
Susceptibility and dilution effects of the kagome bi-layer geometrically frustrated network. A Ga-NMR study of SrCr_(9p)Ga_(12-9p)O_(19)
L. Limot, P. Mendels, G. Collin +5
We present an extensive gallium NMR study of the geometrically frustrated kagome bi-layer compound SrCr_(9p)Ga_(12-9p)O_(19) (Cr^3+, S=3/2) over a broad Cr-concentration range (.72…
Many-polaron states in the Holstein-Hubbard model
Laurent Proville, S. Aubry
A variational approach is proposed to determine some properties of the adiabatic Holstein-Hubbard model which describes the interactions between a static atomic lattice and an asse…
Incommensurate magnetic ordering in Sr_2Ru_(1-x)Ti_xO_4
M. Braden, O. Friedt, Y. Sidis +3
In the spin excitation spectrum is dominated by incommensurate fluctuations at q=(0.3 0.3 q), which arise from Fermi-surface nesting. We show that upon Ti subst…
