Fullerenes, containing five- and six-membered carbon rings, of which C-60 and C-70 are the prominent members, exhibit phase transitions associated with orientational ordering. When C-60 is suitably doped with electrons, ...

Modulation-free BiPbSrLCuO6 (L = La, Pr, Nd) and BiPbSr2YCu2O8, which are isotypic with the n = 1 and 2 members of the Bi2Sr2Ca(n-1)Cu(n)O2n+4 family, have been prepared and characterized. These parent compounds are ...

C60.TDAE (TDAE = tetrakis(dimethylamino)ethylene) with a T(c) of approximately 16K is probably the best example of an organic molecular ferromagnet known to date. Based on ESR studies, we demonstrate that C60.TDAE is a ...

Three one-dimensional zinc phosphates, [C5N2H14][Zn(HPO4)2], I, [C10N4H26][Zn(HPO4)2].2H2O II, and [C4N2H6]2[Zn(HPO4)], III, have been prepared employing hydro/solvothermal methods in the presence of organic amines. While ...

While C60 interacts with aromatic amines such as dimethylaniline in the ground state, C70 does not. Fluorescence spectroscopic studies, including lifetime measurements, show the formation of exciplexes of both C60 and C70 ...

Electron transport and magnetic properties of the cation-deficientcompositions of LaMnO3with the nominal formulae La1−δMnO3(0.0 ≤ δ ≤ 0.2) and LaM1−δ′O3(0.0 ≤ δ′ ≤ 0.2) were investigated after their defect structures were ...

Hexagonal, cubic and lamellar aluminoborate mesophases containing octahedral aluminium and tetrahedral boson are prepared and characterized for the first time.

Crystal structures of the hydrogen bonded, 1:1 molecular complexes of malonic, glutaric, adipic, thiodiglycolic and thiodipropionic acids with 4,4'-bipyridyl have been investigated in detail. All the dicarboxylic acids ...

Mixed cobalt-copper spinel ferrites CoxCu1-xFe2O4 with acicular shape, prepared from oxalate precursors at moderate temperatures, have been investigated by several techniques to relate the coercivity With structure. The ...

We report the observation of substantial thermal relaxation in a single crystal of the charge ordered system Pr0.63Ca0.37MnO3 in an applied magnetic field of H = 8 T. The relaxation is observed when the temperature is ...
