The synthesis of ferromagnetic La0.75Ca0.25MnO 3 nanowires by a sol-gel method
(National Institute of Optoelectronics, 2010) Atalay F.E.; Yagmur V.; Atalay S.; Kaya H.; Tar S.; Avsar D.
In this study, densely packed a0.75Ca0.25MnO 3 (LCMO) nanowires were synthesized within a porous anodic aluminum oxide (AAO) template by means of a sol-gel method using nitrate as raw material and ethylene glycol as the chelating agent. It was observed from measurements of hysteresis curves that the magnetic behavior of the LCMO nanowire arrays was strongly dependent on the pH of the solution. As it has been reported that bulk polycrystalline a0.75Ca0.25MnO3 samples have a Curie temperature of 224 K [1], it is interesting to find that nanowires produced at pH 3 show ferromagnetic properties at room temperature.
