Growth of large La2-xSrxNiO4+delta single crystals by the floating-zone technique

We report on an investigation into the growth of large, high-quality single crystals of La2-xSrxNiO4+ (x = 0-0.5) by the floating zone technique. The results of attempts to grow crystals in different atmospheres are discussed. The oxygen non-stoichiometry (delta) of the as-grown crystals is found to...

الملخص:We report on an investigation into the growth of large, high-quality single crystals of La2-xSrxNiO4+ (x = 0-0.5) by the floating zone technique. The results of attempts to grow crystals in different atmospheres are discussed. The oxygen non-stoichiometry (delta) of the as-grown crystals is found to decrease with the Sr substitution level. Magnetic and electrical transport measurements on the crystals are reported. (C) 2002 Elsevier Science B.V. All rights reserved.
