AB  - The single-phase polycrystalline samples of Y-2(Cu1-xMgx)(2)O-5, x = 0.0, 0.05, 0.15 were successfully synthesized by a modified self-propagating high temperature synthesis. Effects of Mg+2 substitution for Cu+2 in metamagnetic Y2Cu2O5 on its crystal structure and magnetic properties have been analyzed by X-ray diffraction and magnetic measurements performed within 2-300 K range. Mg doping was found to introduce small distortions in the main intradimmer superexchange paths so that ferromagnetic correlations decrease with Mg concentration. More significant impact of Cu substitution was found on the low temperature magnetism due to the breaking of infinite Cu-O chains. The formation of finite size chains introduces low temperature paramagnetic contribution and reduction in Neel temperature. Overall results give a strong indication that the antiferromagnetic ordering as well as metamagnetism persists up to the 15% of the Mg concentration. (C) 2013 Elsevier B.V. All rights reserved.

AB  - Polycrystalline samples of Y2Cu2O5 were for the first time sintered from precursors obtained by two combustion routes - the glycine-nitrate method (sample S1) and a modified self-propagating high-temperature synthesis (sample S2). The detailed X-ray diffraction analysis has confirmed that both samples are well crystallized and single phase, with the high crystallization degree and cation ordering within a Cu sublattice. Magnetic characterization has shown magnetic behavior typical of pure Y2Cu2O5. The distinctive advantages of these new synthesis routes in comparison to the ceramic sintering are in simplification of the overall procedure as well as in a significant reduction of synthesis duration from several days down to 31 h (S1) or 12 h (S2).
