Anisotropic Lattice Compression and Pressure-Induced Electronic Phase Transitions in Sr $_{2}$ IrO $_{4}$

K. Samanta, R. Tartaglia, U. F. Kaneko +2

The crystal lattice of Sr $_{2}$ IrO $_{4}$ is investigated with synchrotron X-ray powder diffraction under hydrostatic pressures up to $P = 43$ GPa and temperatures down to $20$ K. The tet…

Crystal structure, cobalt and iron speciation and oxygen non-stoichiometry of La0.6Sr0.4Co1-yFeyO3-d nanorods for IT-SOFC cathodes

Augusto E. Mejía Gómez, Joaquín Sacanell, Cristián Huck-Iriart +7

Single-phased La0.6Sr0.4Co1-yFeyO3-d (y = 0.2, 0.5, 0.8) nanorods exhibiting the rhombohedral perovskite-type phase were synthesized by a pore-wetting technique. We studied their c…

Possible quantum paramagnetism in compressed Sr $_{2}$ IrO $_{4}$

D. Haskel, G. Fabbris, J. H. Kim +9

The effect of compression on the magnetic ground state of Sr $_{2}$ IrO $_{4}$ is studied with x-ray resonant techniques in the diamond anvil cell. The weak interlayer exchange coupling b…

The zero-field-cooled exchange bias effect in phase-segregated La $_{2 - x}$ A $_{x}$ CoMnO $_{6 - δ}$ (A = Ba, Ca, Sr; x = 0, 0.5)

L. T. Coutrim, D. Rigitano, C. Macchiutti +9

In the zero-field-cooled exchange bias (ZEB) effect the unidirectional magnetic anisotropy is set at low temperatures even when the system is cooled in the absence of external magn…

Nematic state in CeAuSb $_{2}$

S. Seo, Xiaoyu Wang, S. M. Thomas +9

At ambient pressure and zero field, tetragonal CeAuSb $_{2}$ hosts stripe antiferromagnetic order at $T_{N} = 6.3$ K. Here we first show via bulk thermodynamic probes and x-ray diff…

Phase Transition and Electronic Structure Investigation of MoS $_{2}$ -rGO Nanocomposite Decorated with AuNPs

Yunier Garcia-Basabe, Gabriela F. Peixoto, Daniel Grasseschi +5

In this work a simple approach to transform MoS $_{2}$ from its metallic (1T' to semiconductor 2H) character via gold nanoparticle surface decoration of a MoS $_{2}$ graphene oxide (rGO)…
