By decomposing the block copolymer and inducing crystallization of the spinel phase, we successfully produce films exhibiting quasi\u2010hexagonal arrays of pores with an average diameter ranging from 60 to 80\u00a0nm. The resulting nanopatterned porous thin films demonstrate exceptional orderliness, as the pores are intricately designed by the cobalt ferrite grains, and the platinum substrate offers complete accessibility in the pore area. Our findings reveal high magnetization values, comparable to those of bulk CoFe<jats:sub>2<\/jats:sub>O<jats:sub>4<\/jats:sub>, in the dense film. Additionally, in the case of the nanopatterned porous film, we observed a distinctive contribution of perpendicular magnetization. This innovative approach holds great promise for advanced magnetization and thin\u2010film engineering applications.<\/jats:p>","DOI":"10.1002\/nano.202300113","type":"journal-article","created":{"date-parts":[[2023,12,9]],"date-time":"2023-12-09T18:39:07Z","timestamp":1702147147000},"source":"Crossref","is-referenced-by-count":2,"title":["Quasi\u2010hexagonal nanopatterned porous cobalt ferrite thin films prepared via block copolymer self\u2010assembly"],"prefix":"10.1002","volume":"5","author":[{"given":"Alichandra","family":"Castro","sequence":"first","affiliation":[{"name":"CICECO \u2013 Aveiro Institute of Materials Department of Materials and Ceramic Engineering University of Aveiro  Aveiro Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9006-4443","authenticated-orcid":false,"given":"Liliana P.","family":"Ferreira","sequence":"additional","affiliation":[{"name":"Department of Physics University of Coimbra  Coimbra Portugal"},{"name":"Biosystems and Integrative Sciences Institute (BioISI) FCUL Universidade de Lisboa  Lisboa Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5373-2753","authenticated-orcid":false,"given":"Margarida","family":"Godinho","sequence":"additional","affiliation":[{"name":"Biosystems and Integrative Sciences Institute (BioISI) FCUL Universidade de Lisboa  Lisboa Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9419-2717","authenticated-orcid":false,"given":"Brian J.","family":"Rodriguez","sequence":"additional","affiliation":[{"name":"School of Physics &amp;
