Dzyaloshinskii-Moriya Interaction and Dipole-Exchange Curvature Effects on the Spin-Wave Spectra of Magnetic Nanotubes
B. Mimica-Figari, P. Landeros, R. A. Gallardo
This work explores spin-wave dynamics in magnetic nanotubes, focusing on the influence of the Dzyaloshinskii-Moriya interaction and curvature. The study uses analytical methods to…
Nonreciprocal Spin-Wave Propagation in Anisotropy-Graded Iron Films Prepared by Nitrogen Implantation
L. Christienne, J. Jiménez-Bustamante, P. Rovillain +8
Gradual modification of the magnetic properties in ferromagnetic films has recently been proposed as an effective method to channel and control spin waves for the development of ne…
Finite-element dynamic-matrix approach for propagating spin waves: Extension to mono- and multilayers of arbitrary spacing and thickness
Lukas Körber, Alexander Hempel, Andreas Otto +4
In our recent work [AIP Adv. 11, 095006], we presented an efficient numerical method to compute dispersions and spatial mode profiles of spin waves propagating in waveguides with t…
Magnetization dynamics in synthetic antiferromagnets: Role of dynamical energy and mutual spin pumping
S. Sorokin, R. A. Gallardo, C. Fowley +8
We investigate magnetization dynamics in asymmetric interlayer exchange coupled Py/Ru/Py trilayers using both vector network analyzer-based and electrically detected ferromagnetic…
Spin waves in thin films and magnonic crystals with Dzyaloshinskii-Moriya interactions
Rodolfo A. Gallardo, David Cortés-Ortuño, Roberto E. Troncoso +1
The influence of the Dzyaloshinskii-Moriya interaction in ultra-thin ferromagnetic films and chiral magnonic crystals on the behavior of spin waves is reviewed. During the last dec…
Symmetry and localization properties of defect modes in magnonic superlattices
Rodolfo A. Gallardo, Tobias Schneider, Alejandro Roldán-Molina +5
Symmetry and localization properties of defect modes of a one-dimensional bi-component magnonic superlattice are theoretically studied. The magnonic superlattice can be seen as a p…
Emission and Propagation of Multi-Dimensional Spin Waves with nanoscale wavelengths in Anisotropic Spin Textures
V. Sluka, T. Schneider, R. A. Gallardo +15
Spin waves offer intriguing novel perspectives for computing and signal processing, since their damping can be lower than the Ohmic losses in conventional CMOS circuits. For contro…
Flat Bands, Indirect Gaps, and Unconventional Spin-Wave Behavior Induced by a Periodic Dzyaloshinskii-Moriya Interaction
R. A. Gallardo, D. Cortés-Ortuño, T. Schneider +7
Periodically patterned metamaterials are known for exhibiting wave properties similar to the ones observed in electronic band structures in crystal lattices. In particular, periodi…
The role of the internal demagnetizing field in a surface-modulated magnonic crystal
Manuel Langer, Falk Röder, Rodolfo A. Gallardo +9
Magnonic crystals with locally alternating properties and specific periodicities exhibit interesting effects, such as a multitude of different spin-wave states and large band gaps.…
Spin-wave spectra in periodically surface-modulated ferromagnetic thin films
R. A. Gallardo, M. Langer, A. Roldán-Molina +4
This article presents theoretical results for the dynamic response of periodically surface-modulated ferromagnetic thin films. For such system, the role of the periodic dipolar fie…
