Graded Index Confined Spin Waves in an Intermediate Domain Wall
D. Osuna Ruiz, A. P. Hibbins, F. Y. Ogrin
We propose a mathematical model for describing propagating confined modes in domain walls of intermediate angle between domains. The proposed model is derived from the linearised B…
Hippopede curves for modelling radial spin waves in an azimuthal graded magnonic landscape
D. Osuna Ruiz, A. P. Hibbins, F. Y. Ogrin
We propose a mathematical model for describing radially propagating spin waves emitted from the core region in a magnetic patch with n vertices in a magnetic vortex state. The azim…
Time-domain imaging of curling modes in a confined magnetic vortex and a micromagnetic study exploring the role of spiral spin waves emitted by the core
D. Osuna Ruiz, P. S. Keatley, J. R. Childress +4
The curling spin wave modes of a ferromagnetic vortex confined to a microscale disc have been directly imaged in response to a microwave field excitation using time-resolved scanni…
Dynamics of Spiral Spin Waves in Magnetic Nano-patches: Influence of Thickness and Shape
D. Osuna Ruiz, E. Burgos Parra, N. Bukin +5
We explore the dynamics of spiral spin waves in Permalloy nano-elements with variable aspect ratio of geometric dimensions, and their potential use as improved spin wave emitters w…
