Galdámez, Antonio; López-Vergara, Fernanda; Barahona, Patricia; Manríquez, Victor; Ávila, Ricardo E. (2012)The new solid solutions AgPbSb 1 - x Bi x S 3 were prepared by solid state reactions. The phases were characterized by powder X-ray diffractions (XRD), scanning electron microscopy, and thermal analysis. The XRD patterns ...
Synthesis and magnetic properties of chromium-based cu(cr2-xtix)s4 thiospinels and their deficient structures cu1-yoycr2-xtixs4 obtained by copper extraction Barahona, Patricia; Galdámez Silva, Antonio; López Vergara, Fernanda; Manríquez Castro, Víctor; Peña, Octavio (Sociedad Chilena de Quimica, 2014)The crystalline structure of spinels is extremely flexible due to the presence of several sublattices in which the cations can be distributed and localized in different crystallographic sites depending on their sizes, ...
