Abstract
The results of the synthesis and characterization of the optimally doped La1.85Ca0.15(Cu1−xNix)O4-δ solid solution with x = 0, 0.1, 0.2 and 0.3 are reported. The versatility of these La1.85Ca0.15(Cu1−xNix)O4−δ materials is explained on the basis of structural features and the ability to accommodate oxygen nonstoichiometry. According to powder X-ray and neutron diffraction data, La1.85Ca0.15(Cu1−xNix)O4−δ adopts the tetragonal structure with oxygen vacancies occurring preferentially at the Oap sites within the {(La/Ca)O} layers of the perovskite blocks and the oxygen deviation from stoichiometry δ was found to be δ=0.0905(6). The bulk conductivity indicated an Arrhenius-type thermally activated process and oxygen vacancies are the possible ionic charge carriers at T=270 °C. An increase of the conductivity was detected when Ni was introduced. With nickel ratio variation, a strong correlation was observed between the Cu(Ni)-Oap apical bond length variation and the conductivity variation through controlling the O2− ion migration.

The versatility of these La1.85Ca0.15(Cu1−xNix)O4−δ materials is explained on the basis of structural features and the ability to accommodate oxygen nonstoichiometry. According to powder X-ray and neutron diffraction data, La1.85Ca0.15(Cu1−xNix)O4−δ adopts the tetragonal structure with oxygen vacancies occurring preferentially at the Oap sites within the {(La/Ca)O} layers of the perovskite blocks and the oxygen deviation from stoichiometry δ was found to be δ=0.0905(6). The bulk conductivity indicated an Arrhenius-type thermally activated process and oxygen vacancies are the possible ionic charge carriers at T=270 °C. An increase of the conductivity was detected when Ni was introduced. With nickel ratio variation, a strong correlation was observed between the Cu(Ni)-Oap apical bond length variation and the conductivity variation through controlling the O2− ion migration.</div></front></TEI><hal api="V3"> <titleStmt> <title xml:lang="en">Influence of nickel doping on oxygen-ionic conductivity of the n = 1 Ruddlesden-Popper Phases La1.85Ca0.15(Cu1−xNix)O4−δ (δ = 0.0905)</title> <author role="aut"> <persName> <forename type="first">Adnene</forename> <surname>Midouni</surname> </persName> <idno type="halauthorid">1365646</idno> <affiliation ref="#struct-462010"></affiliation> <affiliation ref="#struct-462013"></affiliation> </author> <author role="aut"> <persName> <forename type="first">Mohamed Ikbal</forename> <surname>Houchati</surname> </persName> <idno type="halauthorid">1365647</idno> <affiliation ref="#struct-462010"></affiliation> <affiliation ref="#struct-462011"></affiliation> </author> <author role="aut"> <persName> <forename type="first">Walid Belhaj</forename> <surname>Othman</surname> </persName> <idno type="halauthorid">1365648</idno> <affiliation ref="#struct-462012"></affiliation> </author> <author role="aut"> <persName> <forename type="first">Nassira</forename> <surname>Chniba-Boudjada</surname> </persName> <idno type="halauthorid">290926</idno> <affiliation ref="#struct-446826"></affiliation> </author> <author role="aut"> <persName> <forename type="first">Monica</forename> <surname>Ceretti</surname> </persName> <idno type="halauthorid">677217</idno> <affiliation ref="#struct-24492"></affiliation> </author> <author role="aut"> <persName> <forename type="first">Werner</forename> <surname>Paulus</surname> </persName> <idno type="halauthorid">427439</idno> <affiliation ref="#struct-24492"></affiliation> </author> <author role="aut"> <persName> <forename type="first">Mouna</forename> <surname>Jaouadi</surname> </persName> <idno type="halauthorid">1365649</idno> <affiliation ref="#struct-462010"></affiliation> </author> <author role="aut"> <persName> <forename type="first">Ahmed Hichem </forename> <surname>Hamzaoui </surname> </persName> <idno type="halauthorid">1365650</idno> <affiliation ref="#struct-462010"></affiliation> </author> <editor role="depositor"> <persName> <forename>Monica</forename> <surname>Ceretti</surname> </persName> <email type="md5">5c61e08e108adade87aa207b074dea6b</email> <email type="domain">univ-montp2.fr</email> </editor> </titleStmt> <editionStmt> <edition n="v1" type="current"> <date type="whenSubmitted">2016-07-20 15:11:07</date> <date type="whenModified">2016-08-16 10:34:49</date> <date type="whenReleased">2016-07-20 15:11:07</date> <date type="whenProduced">2016</date> </edition> <respStmt> <resp>contributor</resp> <name key="181810"> <persName> <forename>Monica</forename> <surname>Ceretti</surname> </persName> <email type="md5">5c61e08e108adade87aa207b074dea6b</email> <email type="domain">univ-montp2.fr</email> </name> </respStmt> </editionStmt> <publicationStmt> <distributor>CCSD</distributor> <idno type="halId">hal-01347172</idno> <idno type="halUri">https://hal.archives-ouvertes.fr/hal-01347172</idno> <idno type="halBibtex">midouni:hal-01347172</idno> <idno type="halRefHtml">Journal of Solid State Chemistry, Elsevier, 2016, 240, pp.101-108. <10.1016/j.jssc.2016.05.017></idno> <idno type="halRef">Journal of Solid State Chemistry, Elsevier, 2016, 240, pp.101-108. <10.1016/j.jssc.2016.05.017></idno> </publicationStmt> <seriesStmt> <idno type="stamp" n="CNRS">CNRS -
