NdNiO3 ceramic, 260 nm and 110 nm thin films deposited onto (001)-oriented LaAlO3 substrates were studied to unravel the effect of structural symmetry breaking on the electronic phase transition. Resistivity measurements evidence the coexistence of metallic and insulating states below the TMI, while magnetization measurements confirm the expected TMI = TN for all samples. The structural symmetry was investigated across the MIT, through Raman scattering spectroscopy, with the orthorhombic Pnma phase being found at high temperatures, but the emergence of the monoclinic P21\/n phase only occurring well below TMI, which is an unexpected experimental result since the structural transition has been understood as a necessary trigger for the MIT. These experimental results, which are noticeably independent of the sample type\/quality, imply a temperature difference between the structural and electronic\/magnetic ordering, thus contrasting with current theoretical models.<\/p>","DOI":"10.21203\/rs.3.rs-2514717\/v1","type":"posted-content","created":{"date-parts":[[2023,2,20]],"date-time":"2023-02-20T02:24:49Z","timestamp":1676859889000},"source":"Crossref","is-referenced-by-count":0,"title":["The role of structural distortions in triggering the metal to insulator transition in NdNiO3"],"prefix":"10.21203","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9154-3833","authenticated-orcid":false,"given":"Mariana","family":"Gomes","sequence":"first","affiliation":[{"name":"IFIMUP and IN-Institute of Nanoscience and Nanotechnology, Physics and Astronomy Department of Faculty of Sciences of University of Porto"}]},{"given":"Manjunath","family":"Balagopalan","sequence":"additional","affiliation":[{"name":"IFIMUP and IN-Institute of Nanoscience and Nanotechnology, Physics and Astronomy Department of Faculty of Sciences of University of Porto"}]},{"given":"Rui","family":"Vilarinho","sequence":"additional","affiliation":[{"name":"IFIMUP and IN-Institute of Nanoscience and Nanotechnology, Physics and Astronomy Department of Faculty of Sciences of University of Porto"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2845-7216","authenticated-orcid":false,"given":"Abderrazzak Ait","family":"Bassou","sequence":"additional","affiliation":[{"name":"Centro de Qu\u00edmica-Vila Real, ECVA, Chemistry Department, Universidade de Tr\u00e1s-os-Montes e Alto Douro"}]},{"given":"Bruna","family":"Silva","sequence":"additional","affiliation":[{"name":"Departamento de F\u00edsica, Universidade do Minho"}]},{"given":"Jo\u00e3o","family":"Oliveira","sequence":"additional","affiliation":[{"name":"Departamento de F\u00edsica, Universidade do Minho"}]},{"given":"Bernardo","family":"Almeida","sequence":"additional","affiliation":[{"name":"Departamento de F\u00edsica, Universidade do Minho"}]},{"given":"Ab\u00edlio","family":"Almeida","sequence":"additional","affiliation":[{"name":"IFIMUP and IN-Institute of Nanoscience and Nanotechnology, Physics and Astronomy Department of Faculty of Sciences of University of Porto"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8577-1071","authenticated-orcid":false,"given":"Jens","family":"Kreisel","sequence":"additional","affiliation":[{"name":"University of Luxembourg"}]},{"given":"Pedro","family":"Tavares","sequence":"additional","affiliation":[{"name":"Centro de Qu\u00edmica-Vila Real, ECVA, Chemistry Department, Universidade de Tr\u00e1s-os-Montes e Alto Douro"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6435-3604","authenticated-orcid":false,"given":"Jorge","family":"\u00cd\u00f1iguez","sequence":"additional","affiliation":[{"name":"LIST"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4659-7503","authenticated-orcid":false,"given":"Joaquim","family":"Moreira","sequence":"additional","affiliation":[{"name":"IFIMUP and IN-Institute of Nanoscience and Nanotechnology, Physics and Astronomy Department of Faculty of Sciences of University of Porto"}]}],"member":"297","container-title":[],"original-title":[],"link":[{"URL":"https:\/\/www.researchsquare.com\/article\/rs-2514717\/v1","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.researchsquare.com\/article\/rs-2514717\/v1.html","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,2,20]],"date-time":"2023-02-20T02:24:49Z","timestamp":1676859889000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.researchsquare.com\/article\/rs-2514717\/v1"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2023,2,20]]},"references-count":0,"URL":"https:\/\/doi.org\/10.21203\/rs.3.rs-2514717\/v1","relation":{},"subject":[],"published":{"date-parts":[[2023,2,20]]},"subtype":"preprint"}}
