A simple solvothermal synthesis of MFe2O4 (M=Mn, Co and Ni) nanoparticles
(Elsevier, 2009-10)
[Abstract] Nanoparticles of MFe2O4 (M=Mn, Co and Ni), with diameters ranging from 5 to 10 nm, have been obtained through a solvothermal method. In this synthesis, an alcohol (benzyl alcohol or hexanol) is used as both a ...
Studies on the power factor of (Ba,Sr)Co2+xRu4−xO11 compounds
(Elsevier, 2011-02)
[Abstract] We have prepared polycrystalline single-phase ACo2+xRu4−xO11 (A = Sr, Ba; 0 ≤ x ≤ 0.5) using the ceramic method and we have studied their structure, electrical resistivity and Seebeck coefficient, in order to ...
IR characterization of Ln2−xSrxCoO4 (x≥1; Ln=La, Nd) oxides
(Elsevier, 2001-07)
[Abstract] We have recorded the FTIR spectra of powder samples of Ln2−xSrxCoO4 (Ln=La, Nd) at room temperature. We have identified the infrared active modes (3A2u+4Eu), and analyzed how they change as a function of Ln and ...
Near Room Temperature Dielectric Transition in the Perovskite Formate Framework [(CH₃)₂NH₂][Mg(HCOO)₃]
(The Royal Society of Chemistry, 2012-05)
[Abstract] We report that the hybrid organic–inorganic compound [(CH₃)₂NH₂][Mg(HCOO)₃] shows a marked dielectric transition around Tₜ ∼ 270 K, associated to a structural phase transition from SG R[3 with combining macron]c ...
Thermal Decomposition of [AH][M(HCOO)₃] Perovskite-Like Formates
(MDPI, 2021-05-02)
[Abstract] A systematic study of the thermal decomposition of hybrid perovskites of formula [AH][M(HCOO)₃] under inert atmosphere was performed by means of thermogravimetry and simultaneous infrared spectroscopy of the ...
Magnetoelectric behavior in the complex CaMn7O12 perovskite
(Elsevier, 2009)
[Abstract] We report a magnetoelectric effect in the double perovskite CaMn7O12, that shows a complex magnetic behavior below 90 K with two magnetic phases coexisting (one ferrimagnetic and the other modulated). A second ...
Multifunctional Properties and Multi-Energy Storage in the [(CH₃)₃S][FeCl₄] Plastic Crystal
(Royal Society of Chemistry (UK), 2020-08-28)
[Abstract] In this work, we report a new halometallate [(CH₃)₃S][FeCl₄] with plastic crystal behaviour as a new material for multi-energy storage. This material undergoes a first-order solid–solid plastic crystal phase ...
Pressure-Induced Reversible Framework Rearrangement and Increased Polarization in the Polar [NH₄[Cd(HCOO)₃] Hybrid Perovskite
(Royal Society of Chemistry (UK), 2019-07-18)
[Abstract] In this work, we study the structural changes of the polar [NH₄[Cd(HCOO)₃] hybrid perovskite under external hydrostatic pressure. We report a reversible framework rearrangement as a function of pressure characterized ...
Unveiling Barocaloric Potential in Organometallic-Sandwich Compounds [Cp₂M][PF₆] (M: Fe³⁺, Co³⁺)
(Royal Society of Chemistry (UK), 2024-07-30)
[Abstract] Organometallic-sandwich salts are well-known materials that undergo order–disorder phase transitions, leading to a high-temperature phase characterized by the total or partial disorder of ionic species. Their ...
Hybrid Lead Halide [(CH₃)₂NH₂]PbX₃ (X = Cl⁻ and Br⁻) Hexagonal Perovskites With Multiple Functional Properties
(Royal Society of Chemistry (UK), 2019-07-22)
[Abstract] We have been able to prepare two new lead halides with the formula DMAPbX₃ (where DMA is dimethylammonium and X is Cl⁻ or Br⁻), which display a 4H-hexagonal perovskite polytype, an unusual crystal structure in ...
