However, how magnetic interactions modulate mechanical properties is, to date, not fully understood. Through a comprehensive Monte Carlo investigation, this study demonstrates how the mechanical properties of self\u2010assembled magnetic nanocubes can be controlled intrinsically by the nanoparticle magnetocrystalline anisotropy (MA), as well as by the superstructure shape anisotropy, without any need for changes in structural design (i.e., nanoparticle size, shape, and packing arrangement). A low MA\u2010to\u2010dipolar energy ratio, as found in iron oxide and permalloy systems, favors isotropic mechanical superstructure stabilization, whereas a high ratio yields magnetically blocked nanoparticle macrospins which can give rise to metastable <jats:italic>superferromagnetism<\/jats:italic>, as expected in cobalt ferrite simple cubic supercrystals. Such full parallel alignment of the particle moments is shown to induce mechanical anisotropy, where the superior high\u2010strength axis can be remotely reconfigured by means of an applied magnetic field. The new concepts developed here pave the way for the experimental realization of smart magneto\u2010micromechanical systems (based, e.g., on the permanent super\u2010magnetostriction effect illustrated here) and inspire new design rules for applied functional materials.<\/jats:p>","DOI":"10.1002\/advs.202002683","type":"journal-article","created":{"date-parts":[[2021,2,18]],"date-time":"2021-02-18T14:14:30Z","timestamp":1613657670000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Reconfigurable Mechanical Anisotropy in Self\u2010Assembled Magnetic Superstructures"],"prefix":"10.1002","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3131-5905","authenticated-orcid":false,"given":"Verner","family":"H\u00e5konsen","sequence":"first","affiliation":[{"name":"NTNU Nanomechanical Lab Department of Structural Engineering Norwegian University of Science and Technology (NTNU)  Trondheim 7491 Norway"}]},{"given":"Gurvinder","family":"Singh","sequence":"additional","affiliation":[{"name":"School of Biomedical Engineering University of Sydney  Sydney NSW 2008 Australia"},{"name":"Sydney Nano Institute University of Sydney  Sydney NSW 2008 Australia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9075-1697","authenticated-orcid":false,"given":"Jos\u00e9 A.","family":"De Toro","sequence":"additional","affiliation":[{"name":"Instituto Regional de Investigaci\u00f3n Cient\u00edfica Aplicada (IRICA) and Departamento de F\u00edsica Aplicada Universidad de Castilla\u2010La Mancha  Ciudad Real 13071 Spain"}]},{"given":"Peter S.","family":"Normile","sequence":"additional","affiliation":[{"name":"Instituto Regional de Investigaci\u00f3n Cient\u00edfica Aplicada (IRICA) and Departamento de F\u00edsica Aplicada Universidad de Castilla\u2010La Mancha  Ciudad Real 13071 Spain"}]},{"given":"Erik","family":"Wahlstr\u00f6m","sequence":"additional","affiliation":[{"name":"Center for Quantum Spintronics Department of Physics Norwegian University of Science and Technology (NTNU)  Trondheim 7491 Norway"}]},{"given":"Jianying","family":"He","sequence":"additional","affiliation":[{"name":"NTNU Nanomechanical Lab Department of Structural Engineering Norwegian University of Science and Technology (NTNU)  Trondheim 7491 Norway"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9557-3455","authenticated-orcid":false,"given":"Zhiliang","family":"Zhang","sequence":"additional","affiliation":[{"name":"NTNU Nanomechanical Lab Department of Structural Engineering Norwegian University of Science and Technology (NTNU)  Trondheim 7491 Norway"}]}],"member":"311","published-online":{"date-parts":[[2021,2,15]]},"reference":[{"key":"e_1_2_6_1_1","doi-asserted-by":"publisher","DOI":"10.1002\/adma.200401559"},{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1021\/ja308962w"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1126\/science.1254132"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1039\/C8MH01112E"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1021\/jp035665c"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1038\/nnano.2009.453"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevB.86.144402"},{"key":"e_1_2_6_8_1","doi-asserted-by":"publisher","DOI":"10.1007\/s12274-014-0541-9"},{"key":"e_1_2_6_9_1","doi-asserted-by":"publisher","DOI":"10.1021\/acs.chemmater.9b03268"},{"key":"e_1_2_6_10_1","doi-asserted-by":"publisher","DOI":"10.1002\/smll.201000114"},{"key":"e_1_2_6_11_1","doi-asserted-by":"publisher","DOI":"10.1038\/nature09188"},{"key":"e_1_2_6_12_1","doi-asserted-by":"publisher","DOI":"10.1038\/nmat4553"},{"key":"e_1_2_6_13_1","doi-asserted-by":"publisher","DOI":"10.1002\/adfm.201904825"},{"key":"e_1_2_6_14_1","doi-asserted-by":"publisher","DOI":"10.1038\/srep03161"},{"key":"e_1_2_6_15_1","doi-asserted-by":"publisher","DOI":"10.1021\/nl500904a"},{"key":"e_1_2_6_16_1","doi-asserted-by":"publisher","DOI":"10.1021\/nl035004r"},{"key":"e_1_2_6_17_1","doi-asserted-by":"publisher","DOI":"10.1021\/nn3052617"},{"key":"e_1_2_6_18_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11051-012-1072-5"},{"volume-title":"Nanocolloids: A Meeting Point for Scientists and Technologists","year":"2016","author":"S\u00e1nchez\u2010Dom\u00ednguez M.","key":"e_1_2_6_19_1"},{"key":"e_1_2_6_20_1","doi-asserted-by":"publisher","DOI":"10.1029\/98JB01120"},{"key":"e_1_2_6_21_1","doi-asserted-by":"publisher","DOI":"10.1021\/cm040012"},{"key":"e_1_2_6_22_1","doi-asserted-by":"publisher","DOI":"10.1046\/j.1365-246x.2000.00999.x"},{"key":"e_1_2_6_23_1","doi-asserted-by":"publisher","DOI":"10.1063\/1.2832503"},{"key":"e_1_2_6_24_1","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRev.70.954"},{"volume-title":"Wood Composites","year":"2015","author":"Ansell M.
