    • Crystal structure and magnetic properties of titanium-based CuTi2−xMxS4 and CuCr2−xTixSe4 chalcospinels 
      Barahona Huenchumil, Patricia Mabel; Galdámez Silva, Antonio; López Vergara, F.; Manríquez Castro, Víctor; Peña, O. (Elsevier, 2014)
      CuTi2−xM xS4 (M =Fe, Mn, Co; x =0.3, 0.5) and CuCr2−xTixSe4 (x =0.3, 0.5, 0.7) chalcospinels were synthesized by conventional solid-state reactions. Their crystal structures were determined by single-crystal X-ray ...
    • Cu2Mn1-xCoxSnS4: Novel kesterite type solid solutions 
      López Vergara, F.; Galdámez Silva, Antonio; Manríquez Castro, Víctor; Barahona Huenchumil, Patricia Mabel; Peña, O. (ACADEMIC PRESS INC., 2013-02)
      A new family of Cu2Mn1-xCoxSnS4 chalcogenides has been synthesized by conventional solid-state reactions at 850 degrees C. The reactions products were characterized by powder X-ray diffraction (XRD), energy-dispersive X-ray ...
    • Intercalation of polyethylene oxide PEO in layered MPS3 (M = Ni, Fe) materials 
      Manríquez Castro, Víctor; Barahona Huenchumil, Patricia Mabel; Ruiz, D.; Avila, R. E. (PERGAMON-ELSEVIER SCIENCE, 2005-03-08)
      The intercalation compounds Li-0.96(H2O)(0.77)(PEO)(0.63)Ni0.48PS3 and Li-0.94(H2O)(0.92)(PEO)(0.94)Fe0.48PS3 obtained by the insertion of PEO in MPS3 form lithium-polyethylene oxide complexes containing Li+ exchangeable ...
    • Intra- and inter-network interactions in magnetic oxides 
      Peña, Octavio; Moure, C.; Barahona Huenchumil, Patricia Mabel; Baibich, M.; Martínez, G. (ELSEVIER SCIENCE BV, 2006-10-01)
      Partial substitutions of Mn by a transition metal Me in the rare-earth manganites REMexMn1-xO3 results in the simultaneous presence of Mn3+ and Mn4+, triggering double exchange ferromagnetic mechanisms. The RE sublattice ...
    • Magnetic and structural properties of the chromium-based Mn1−xCdxCr2S4 thiospinel 
      Barahona Huenchumil, Patricia Mabel; Galdámez, Antonio César; Manríquez Castro, Víctor; Peña, Octavio (2009)
      The (Mn1−xCdx)Cr2S4 phases (0≤x≤0.6) have been synthesized from the corresponding elements at 1123 K. These sampleswere characterized by powder X-ray diffraction (XRD) and magnetic susceptibility. The(Mn1−xCdx)Cr2S4 ...
    • Magnetic order in sulfide spinels MnLu1.8Me0.2S4 (Me = Ho, Er, Cr) 
      Barahona Huenchumil, Patricia Mabel; Peña, Octavio (ELSEVIER, 2006-10-01)
      Magnetic properties of sulfide spinels derived from the lutetium manganese thiospinel MnLu2S4 are reported. In this first approach, we have partially substituted lutetium by other lanthanides or by some transition metal ...
    • Magnetic properties and crystal structure of solid-solution Cu2MnxFe1 xSnS4 chalcogenides with stannite-type ... 
      López Vergara, Fernanda; Galdámez Silva, Antonio; Manríquez Castro, Víctor; Barahona Huenchumil, Patricia Mabel; Peña, O. (Wiley, 2014)
      New solid solutions Cu2MnxFe1 xSnS4 were prepared by direct combination of the corresponding elements at 850 8C. The crystal structure of Cu2Mn0.4Fe0.6SnS4 was determined by single-crystal X-ray diffraction. This phase ...
    • Structural characterization and dielectric properties of the solid solutions AgPb(Sb,Bi)S3 
      Galdámez Silva, Antonio; López Vergara, Fernanda; Barahona Huenchumil, Patricia Mabel; Manríquez Castro, Víctor; Avila, Ricardo E. (Springer, 2012)
      The new solid solutions AgPbSb1−xBixS3 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 of ...
    • Synthesis and magnetic properties of chromium‑based cu(cr‑ti)s thiospinels and their deficient structures ... 
      Barahona Huenchumil, Patricia Mabel; Galdámez Silva, Antonio; López Vergara, Fernanda; Manríquez Castro, Víctor; Peña, Octavio (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, ...
