La$_{1.5}$Ca$_{0.5}$CoIrO$_{6}$ is a re-entrant spin-glass (SG) that exhibits antiferromagnetic and ferromagnetic couplings at $T\sim95$ and $\sim86$ K, respectively, and at $T\sim25$ K a SG phase emerges. In this work we investigated the effect of h

La3Co4Sn13 is a superconducting material with transition temperature at Tc = 2.70 K, which presents a superlattice structural transition at T* ~ 150 K, a common feature for this class of compounds. However, for this material, it is not clear that at

The Fe K X-ray absorption near edge structure (XANES) of BaFe2-xCoxAs2 superconductors was investigated. No appreciable alteration in shape or energy position of this edge was observed with Co substitution. This result provides experimental support t
