Mesoscopic crystals of maghemite (γ-Fe2O3) nanoparticles can be arranged into highly ordered body-centered tetragonal lattices of up to a few micrometers. Although measurements on disordered ensembles have been carried out, determining the magnetic properties of individual mesoscopic crystals is challenging due to their small total magnetic moment. Here, we overcome these challenges by utilizing sensitive dynamic cantilever magnetometry to study individual micrometer-sized γ-Fe2O3 mesocrystals. These measurements reveal an unambiguous cubic anisotropy, resulting from the crystalline anisotropy of the constituent maghemite nanoparticles and their alignment within the mesoscopic lattice. The signatures of anisotropy and its origins come to light because we combine the self-assembly of highly ordered mesocrystals with the ability to resolve their individual magnetism. This combination is promising for future studies of the magnetic anisotropy of other nanoparticles, which are too small to investigate individually. 000904911 536__ $$0G:(DE-HGF)POF4-5353$$a5353 - Understanding the Structural and Functional Behavior of Solid State Systems (POF4-535)$$cPOF4-535$$fPOF IV$$x0 000904911 588__ $$aDataset connected to CrossRef, Journals: juser.fz-juelich.de 000904911 7001_ $$0P:(DE-HGF)0$$aPhilipp, S.$$b1 000904911 7001_ $$0P:(DE-Juel1)165357$$aJosten, E.$$b2$$eCorresponding author 000904911 7001_ $$00000-0001-8778-3092$$aLeliaert, J.$$b3$$eCorresponding author 000904911 7001_ $$0P:(DE-HGF)0$$aWetterskog, E.$$b4 000904911 7001_ $$0P:(DE-HGF)0$$aBergström, L.$$b5 000904911 7001_ $$00000-0002-5327-051X$$aPoggio, M.$$b6$$eCorresponding author 000904911 773__ $$0PERI:(DE-600)2844160-6$$a10.1103/PhysRevB.103.014402$$gVol. 103, no. 1, p. 014402$$n1$$p014402$$tPhysical review / B$$v103$$x1098-0121$$y2021 000904911 8564_ $$uhttps://juser.fz-juelich.de/record/904911/files/PhysRevB.103.014402.pdf$$yOpenAccess 000904911 909CO $$ooai:juser.fz-juelich.de:904911$$pdnbdelivery$$pdriver$$pVDB$$popen_access$$popenaire 000904911 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)165357$$aForschungszentrum Jülich$$b2$$kFZJ 000904911 9101_ $$0I:(DE-HGF)0$$60000-0001-8778-3092$$aExternal Institute$$b3$$kExtern 000904911 9131_ $$0G:(DE-HGF)POF4-535$$1G:(DE-HGF)POF4-530$$2G:(DE-HGF)POF4-500$$3G:(DE-HGF)POF4$$4G:(DE-HGF)POF$$9G:(DE-HGF)POF4-5353$$aDE-HGF$$bKey Technologies$$lMaterials Systems Engineering$$vMaterials Information Discovery$$x0 000904911 9141_ $$y2021 000904911 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS$$d2021-05-04 000904911 915__ $$0StatID:(DE-HGF)0160$$2StatID$$aDBCoverage$$bEssential Science Indicators$$d2021-05-04 000904911 915__ $$0StatID:(DE-HGF)1230$$2StatID$$aDBCoverage$$bCurrent Contents - Electronics and Telecommunications Collection$$d2021-05-04 000904911 915__ $$0StatID:(DE-HGF)0600$$2StatID$$aDBCoverage$$bEbsco Academic Search$$d2021-05-04 000904911 915__ $$0LIC:(DE-HGF)APS-112012$$2HGFVOC$$aAmerican Physical Society Transfer of Copyright Agreement 000904911 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR$$bPHYS REV B : 2019$$d2021-05-04 000904911 915__ $$0StatID:(DE-HGF)0113$$2StatID$$aWoS$$bScience Citation Index Expanded$$d2021-05-04 000904911 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection$$d2021-05-04 000904911 915__ $$0StatID:(DE-HGF)9900$$2StatID$$aIF < 5$$d2021-05-04 000904911 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 000904911 915__ $$0StatID:(DE-HGF)0030$$2StatID$$aPeer Review$$bASC$$d2021-05-04 000904911 915__ $$0StatID:(DE-HGF)1150$$2StatID$$aDBCoverage$$bCurrent Contents - Physical, Chemical and Earth Sciences$$d2021-05-04 000904911 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline$$d2021-05-04 000904911 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bClarivate Analytics Master Journal List$$d2021-05-04 000904911 920__ $$lyes 000904911 9201_ $$0I:(DE-Juel1)ER-C-2-20170209$$kER-C-2$$lMaterialwissenschaft u.
