Influence of R-ion size on spin state of Co and magnetic properties of RBaCo2O5.50 cobaltites Frontera Beccaria, Carlos García Muñoz, José Luis Castaño Linares, Óscar Cobalt Metalls de transició Difracció de neutrons Temperatura Materials ferromagnètics Cobalt Transition metals Neutron diffraction Temperature Ferromagnetic materials This work presents a comparative magnetic study of PrBaCo2O5.50 and YBaCo2O5.50. Samples studied have been carefully prepared, specially the PrBaCo2O5.50 one, to avoid the formation of oxygen vacancy disorder. High temperature magnetic measurements indicate different spin states of Co ions in both compounds. Neutron powder diffraction below RT indicate a different succession of magnetic arrangements. 2017-11-29T14:53:54Z 2017-11-29T14:53:54Z 2008-01-30 2017-11-29T14:53:54Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion 0021-8979 https://hdl.handle.net/2445/118274 674418 eng Reproducció del document publicat a: https://doi.org/10.1063/1.2829747 Journal of Applied Physics, 2008, vol. 103, num. 7, p. 07F713-1-07F713-3 https://doi.org/10.1063/1.2829747 (c) American Institute of Physics , 2008 info:eu-repo/semantics/openAccess 1 p. application/pdf application/pdf American Institute of Physics Articles publicats en revistes (Enginyeria Electrònica i Biomèdica)
