Antiferromagnetic order and consequences on the transport properties of BaRuO
Yannick Klein, Gwenaelle Rousse, Françoise Damay +3
Barium ruthenate BaRuO, in which RuO trimers are connected together to form a chequered two-dimensional framework, has been synthesised and its stru…
Two-dimensional fluctuations and competing phases in the stripe-like antiferromagnet BaCoS
Haneen Abushammala, Benjamin Lenz, Benoit Baptiste +5
By means of a combined x-ray diffraction, magnetic susceptibility and specific heat study, we investigate the interplay between orthorhombic distortion and stripe-like antiferromag…
Structural Evolution and Onset of the Density Wave Transition in the CDW Superconductor LaPtSi Clarified with Synchrotron XRD
Elisabetta Nocerino, Irene San Lorenzo, Konstantinos Papadopulos +11
The quasi-2D Pt-based rare earth intermetallic material LaPtSi has attracted attention as it exhibits strong interplay between charge density wave (CDW) and and superconduc…
Direct observation of Jahn-Teller critical dynamics at a charge-order Verwey transition
Vinícius Pascotto Gastaldo, Mala N. Rao, Alexey Bosak +10
By means of diffuse and inelastic x-ray scattering (DS,IXS), we probe directly the charge-ordering (CO) dynamics in the Verwey system (NaMn)MnO, where a peculiar qua…
Tuning Dirac nodes with correlated d-electrons in BaCo_{1-x}Ni_{x}S_{2}
N. Nilforoushan, M. Casula, A. Amaricci +15
Dirac fermions play a central role in the study of topological phases, for they can generate a variety of exotic states, such as Weyl semimetals and topological insulators. The con…
Probing the quantum phase transition in Mott insulator BaCoS_2 tuned by pressure and Ni-substitution
Z. Guguchia, B. A. Frandsen, D. Santos-Cottin +15
We present a muon spin relaxation study of the Mott transition in BaCoS_2 using two independent control parameters: (i) pressure p to tune the electronic bandwidth and (ii) Ni-subs…
Distortion mode anomalies in bulk PrNiO illustrating the potential of symmetry-adapted distortion mode analysis for the study of phase transitions
D. J. Gawryluk, Y. M. Klein, T. Shang +7
The origin of the metal-to-insulator transition in RNiO3 perovskites with trivalent 4f ion has challenged the condensed matter research community for almost three decades. A drawba…
Linear behavior of the optical conductivity and incoherent charge transport in BaCoS2
D. Santos-Cottin, Y. Klein, Ph. Werner +5
Optical conductivity measurements on a BaCoS2 single crystal show an unusual linear behavior over a broad spectral range. In the paramagnetic phase above 300 K, the spectrum shows…
Anomalous metallic state in quasi-two-dimensional BaNiS
David Santos-Cottin, Andrea Gauzzi, Marine Verseils +6
We report on a systematic study of the thermodynamic, electronic and charge transport properties of high-quality single crystals of BaNiS, the metallic end-member of the quasi-…
X-ray crystal structure analysis and the Ru valence of Ba4Ru3O10 single crystals
Taichi Igarashi, Yoshio Nogami, Yannick Klein +5
We present the single-crystalline x-ray diffraction study on the Ba4Ru3O10 consisting of the corner-shared Ru3O12 trimers. The crystal structure is re-determined from 78 to 300 K a…
High-field metamagnetism in the antiferromagnet CeRhSi
W. Knafo, D. Aoki, D. Vignolles +6
A study of the antiferromagnet CeRhSi by torque, magnetostriction, and transport in pulsed magnetic fields up to 50 Tesla and by thermal expansion in static fields up to 13…
