Publicación Acceso Abierto Magnetoelastic Anisotropy Drives Localized Magnetization Reversal in 3D Nanowire Networks(Royal Society of Chemistry, 2025-01) Vivas, Laura G.; Ruiz Clavijo, Alejandra; Caballero Calero, Olga; Navas, David; Ordoñez Cencerrado, Amanda A.; Manzano, Cristina V.; Sanz, Ruy; Martín-González, Marisol; Agencia Estatal de Investigación (España)Three-dimensional magnetic nanowire networks (3DNNs) have shown promise for applications beyond those of their linear counterparts. However, understanding the underlying magnetization reversal mechanisms has been limited. In this study, we present a combined experimental and computational investigation on simplified 3DNNs to address this gap. Our findings reveal a previously unidentified in-plane magnetoelastic anisotropy, validated through comparisons between experimental and simulated magnetic data. Notably, we discovered that magnetization reversal in 3DNNs is driven by highly localized magnetic states, arising from the interplay of exchange and dipolar interactions, magnetoelastic anisotropy, and nanowire microstructure. This discovery challenges the prevailing understanding of magnetization reversal in nickel nanowires. Our work provides critical insights into the magnetic behavior of 3DNNs, opening doors for their tailored design and optimization.
