Ferromagnetic resonance response in square artificial spin ice: roles of geometry in vertex dynamics and magnetic configurations
G. A. Gomez-Iriarte, D. E. Gonzalez-Chavez, R. L. Sommer +1
Artificial spin ice (ASI) represents a class of uniquely structured superlattices comprising geometrically arranged interacting nanomagnets. This arrangement facilitates the explor…
Pure phase BiFeO thin films sputtered over Si: A new route towards high magnetization
G. A. Gomez-Iriarte, C. Labre, L. A. S. de Oliveira +1
We have investigated the structural and magnetic properties of BiFeO (BFO) thin films grown over (100)-oriented Si substrates by rf magnetron sputtering in a new route under O$…
Micromagnetic study of skyrmion stability in confined magnetic structures with perpendicular anisotropy
R. L. Novak, F. Garcia, E. R. P. Novais +2
Skyrmions are emerging topological spin structures that are potentially revolutionary for future data storage and spintronics applications. The existence and stability of skyrmions…
Temperature dependence of the coercive field in single-domain particle systems
W. C. Nunes, W. S. D. Folly, J. P. Sinnecker +1
The magnetic properties of Cu97Co3 and Cu90Co10 granular alloys were measured over a wide temperature range (2 to 300K). The measurements show an unusual temperature dependence of…
