Crossover from individual to collective magnetism in dense nanoparticle systems: local anisotropy versus dipolar interactions
Sánchez, Elena H.; Vasilakaki, Marianna; Lee, Su Seong; Normile, Peter S.; Andersson, Mikael S.; Mathieu, Roland; López Ortega, Alberto ; Pichon, Benoit P.; Peddis, Davide; Binns, Chris; Nordblad, Per; Trohidou, Kalliopi; Nogués, Josep; Toro, José A. de (Nano-Micro, 2022) Artículo / ArtikuluaDense systems of magnetic nanoparticles may exhibit dipolar collective behavior. However, two fundamental questions remain unsolved: i) whether the transition temperature may be affected by the particle anisotropy or ... -
Direct evidence of a graded magnetic interface in bimagnetic core/shell nanoparticles using electron magnetic circular dichroism (EMCD)
Pozo Bueno, Daniel del; Varela, María; Estrader, Marta; López Ortega, Alberto ; Gómez Roca, Alejando; Nogués, Josep; Peiró, Francesca; Estradé, Sònia (American Chemical Society, 2021) Artículo / ArtikuluaInterfaces play a crucial role in composite magnetic materials and particularly in bimagnetic core/shell nanoparticles. However, resolving the microscopic magnetic structure of these nanoparticles is rather complex. Here, ... -
Elucidating individual magnetic contributions in bi-magnetic Fe3O4/Mn3O4 Core/Shell nanoparticles by polarized powder neutron diffraction
Golosovsky, Igor V.; Kibalin, Iurii A.; Gukasov, Arsen; Gómez Roca, Alejando; López Ortega, Alberto ; Estrader, Marta; Vasilakaki, Marianna; Trohidou, Kalliopi; Hansen, T. C.; Puente-Orench, I.; Lelièvre-Berna, E.; Nogués, Josep (Wiley, 2023) Artículo / ArtikuluaHeterogeneous bi-magnetic nanostructured systems have had a sustained interest during the last decades owing to their unique magnetic properties and the wide range of derived potential applications. However, elucidating ...
