    • Electrical and Magnetic Properties of Quaternary Rare Earth Thiophosphate: K4Sm2[PS4]2[P2S6] 
      Manríquez Castro, Víctor; Galdámez Silva, Antonio; Cerda Monje, Andrea; Peña, Octavio; Ávila, Ricardo E. (2009)
      O tiofosfato quaternário de metal alcalino e terra rara K4Sm2[PS4]2[P2S6] foi sintetizado pelo método cerâmico e caracterizado por difratometria de raios X de pó (XRD), microscopia eletrônica de varredura com microanálise ...
    • 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 ...
    • 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, ...
