Magnon Polarons induced by a magnetic field gradient
N. Vidal-Silva, E. Aguilera, A. Roldán-Molina +2
In this work, we report the theoretical possibility of generating magnon polaron excitations through a space-varying magnetic field. The spatial dependence of the magnetic field in…
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…
Spin-wave amplification and lasing driven by inhomogeneous spin transfer torques
R. J. Doornenbal, A. Roldán-Molina, A. S. Nunez +1
We show that an inhomogeneity in the spin-transfer torques in a metallic ferromagnet under suitable conditions strongly amplifies incoming spin waves. Moreover, at nonzero temperat…
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…
Spin-Wave Modes in Transition from a Thin Film to a Full Magnonic Crystal
Manuel Langer, Rodolfo A. Gallardo, Tobias Schneider +7
Spin-wave modes are studied under the gradual transition from a flat thin film to a 'full' (one-dimensional) magnonic crystal. For this purpose, the surface of a pre-patterned 36.8…
