RT Journal Article T1 Mapping the Magnetic Coupling of Self-Assembled Fe3O4 Nanocubes by Electron Holography A1 López Conesa, Lluís A1 Martínez Boubeta, Carlos A1 Serantes Abalo, David A1 Estradé, Sonia A1 Peiró, Francesca K1 Electron holography K1 Magnetic nanoparticles K1 Magnetic hyperthermia AB The nanoscale magnetic configuration of self-assembled groups of magnetite 40 nm cubic nanoparticles has been investigated by means of electron holography in the transmission electron microscope (TEM). The arrangement of the cubes in the form of chains driven by the alignment of their dipoles of single nanocubes is assessed by the measured in-plane magnetic induction maps, in good agreement with theoretical calculations PB MDPI YR 2021 FD 2021 LK http://hdl.handle.net/10347/24433 UL http://hdl.handle.net/10347/24433 LA eng NO Materials 2021, 14(4), 774; https://doi.org/10.3390/ma14040774 NO This research received funding from the Xunta de Galicia, Program for Development of a Strategic Grouping in Materials (AeMAT, Grant No. ED431E2018/08), the Agencia Estatal de Investigación (project PID2019-109514RJ-100), the Spanish Ministry of Economy and Competitiveness, grant number MAT2010-16407, and from the European Union Seventh Framework Programme under Grant Agreement 312483-ESTEEM2 (Integrated Infrastructure Initiative–I3) DS Minerva RD 27 abr 2026
