Evolution of the spectral lineshape at the magnetic transition in Sr2IrO4 and Sr3Ir2O7
Paul Foulquier, Marcello Civelli, Marcelo Rozenberg +8
Sr2IrO4 and Sr3Ir2O7 form two families of spin-orbit Mott insulators with quite different charge gaps and an antiferromagnetic (AF) ground state. This offers a unique opportunity t…
Elasto-Raman scattering: arsenic optical phonon as a probe of nematicity in BaFeAs
J. -C. Philippe, J. Faria, A. Forget +5
We report a Raman scattering study of nematic degrees of freedom in the iron-based superconductor parent compound BaFeAs under tunable uniaxial strain. We demonstrate that…
Incommensurate spin density wave in Co-doped BaFe2As2
P. Bonville, F. Rullier-Albenque, D. Colson +1
57Fe Mossbauer spectroscopy measurements are presented in the underdoped Ba(Fe{1-x}Cox)2As2 series for x=0.014 (T_c < 1.4K) and x=0.03 and 0.045 (T_c ~ 2 and 12K respectively). The…
First Order Transition in the Spin Dynamics of Geometrically Frustrated Yb2Ti2O7
J. A. Hodges, P. Bonville, A. Forget +10
Using neutron diffraction, 170Yb Mossbauer and muSR spectroscopies, we have examined the pyrochlore Yb2Ti2O7 where the Yb3+ S'=1/2 ground state has planar anisotropy. Below ~0.24K,…
