Experimental micromagnetism by vector magnetic tomography

Esta tesis aborda el proceso de reconstrucción de la imanación vectorial tridimensional de materiales magnéticos en la nanoescala. La capacidad de visualizar las texturas magnéticas permite entender y controlar sus propiedades magnéticas, con aplicaciones en sistemas de almacenamiento de datos, sensores magnéticos y la espintrónica.

Coercivity degradation caused by inhomogeneous grain boundaries in sintered Nd-Fe-B permanent magnets

, 2018
Quantitative correlation between intrinsic coercivity and grain boundaries in three dimensions is critical to further improve the performance of sintered Nd-Fe-B permanent magnets. Here, we quantitatively reveal the local composition variation across and

Understanding the Effect of Curvature on the Magnetization Reversal of Three-Dimensional Nanohelices

Comprehending the interaction between geometry and magnetism in three-dimensional (3D) nanostructures is important to understand the fundamental physics of domain wall (DW) formation and pinning.
