Abstract Solid state compounds exhibiting multiple and coupled macroscopic orders, named multiferroics, represent a challenge for both theoretical experimental modern condensed-matter physics. Spins the electric polarisation in conventional magnetic ferroelectric materials can be manipulated on their fundamental timescales, by means of femtosecond laser pulses. In view resounding success popularity all-optical approach, it is only natural to wonder about application this scheme study...
This study investigates the magnetic properties of strontium-doped lanthanum manganites [La1−xSrxMnO3 (LSMO)], focusing on effects doping and synthesis methods. Materials with different Sr-doping concentrations (x = 0, 0.1, 0.2, 0.3) were prepared by citrate–nitrate autocombustion (CNA) coprecipitation synthesis. Magnetization curves exhibit a transition from paramagnetic behavior to long-range ferromagnetic order below Curie temperatures (TC), which increase Sr content due Jahn–Teller...
The heterodimetallic [CuFe] compounds [CuII4(terpy)4Cl5][FeIII(C2O4)3]·10H2O (1;terpy = 2,2′:6′,2′′-terpyridine), [CuII2(H2O)2(terpy)2(C2O4)][CuIIFeIII(CH3OH)(terpy)(C2O4)3]2 (2), and {[Cu2IIFeIII(H2O)(terpy)2(C2O4)7/2]·6H2O}n (3) were obtained using building block approach, from reaction of aqueous solution [Fe(C2O4)3]3– a methanol containing Cu2+ ions terpy by the layering technique. Interestingly, changing only anion starting salt copper(II), Cu(NO3)2·3H2O instead CuCl2·2H2O, an...
Two heterometallic coordination polymers {[NH(CH3)2(C2H5)]8[Mn4Cl4Cr4(C2O4)12]}n (1) and {[NH(CH3)-(C2H5)2]8[Mn4Cl4Cr4(C2O4)12]}n (2) were obtained by slow evaporation of an aqueous solution containing the building block [A]3[Cr(C2O4)3] [A = (CH3)2(C2H5)NH+ or (CH3)(C2H5)2NH+] MnCl2·2H2O. The isostructural compounds comprise irregular two-dimensional (2D) oxalate-bridged anionic layers [Mn4Cl4Cr4(C2O4)12]n8n– with a Shubnikov plane net fes topology designated as (4·82), interleaved...
Seven novel oxalate-based [CuIICrIII] compounds: [Cu4(terpy)4Cl5][Cr(C2O4)3]·9H2O (1; terpy = 2,2':6',2''-terpyridine), {[Cr2Cu4(H2O)2(terpy)4(C2O4)7]·10H2O}n (2), [Cr2Cu4(H2O)2(terpy)4(C2O4)7]·12H2O (3), [Cu(H2O)3(terpy)][CrCu(H2O)(terpy)(C2O4)3]2·9H2O (4), [Cu(H2O)(terpy)(NO3)][CrCu(H2O)(terpy)(C2O4)3]·6H2O (5), [CrCu2(terpy)2(C2O4)3(NO3)]·1.5H2O·CH3OH (6) and [Cr2Cu4(H2O)4(terpy)4(C2O4)6][Cr2Cu2(terpy)2(C2O4)6]·9H2O·CH3OH (7) were obtained from the reaction of an aqueous solution building...
A series of six novel salts 5,6-dichloro-2,3-dicyanosemiquinone (DDQ) radical anions with aromatic cations is studied by structural characterization, magnetization, and conductivity measurements. Different types stacking DDQ radicals, which determine electrical magnetic properties, are observed: regular stacks equidistant radicals (resulting in semiconductivity along the direction stacking), pancake-bonded dimers, isolated mixed comprising cations. General features pancake bonding defined:...
Pure and Co3+-doped BaAl2O4 [Ba(Al1–xCox)2O4, x = 0, 0.0077, 0.0379] powder samples were prepared by a facile hydrothermal route. Elemental analyses static secondary ion mass spectrometry (SIMS), X-ray absorption spectroscopy (XAS) measurements at the Co K-edge, diffraction studies fully correlated, thus addressing complete description of structural complexity powder. Powder (PXRD) patterns indicated that nanocrystalline with hexagonal P63 symmetry. The near-edge structure (XANES) revealed...
Tetrachlorocuprate(II) hybrids of the three anisidine isomers (ortho-, meta-, and para-, or 2-, 3-, 4-methoxyaniline, respectively) were prepared studied in solid state via X-ray diffraction magnetization measurements. Depending on position methoxy group organic cation, subsequently, overall cation geometry, a layered, defective structure comprising discrete tetrachlorocuprate(II) units obtained for ortho-anisidinium hybrids, respectively. In case layered structures, this affords...
