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…
