Frequency-dependent reflection of spin waves from a magnetic inhomogeneity induced by a surface DC-current
T. Neumann, A. A. Serga, B. Hillebrands +1
The reflectivity of a highly localized magnetic inhomogeneity is experimentally studied. The inhomogeneity is created by a dc-current carrying wire placed on the surface of a ferri…
Probing of a parametrically pumped magnon gas with a non-resonant packet of traveling spin waves
T. Neumann, A. A. Serga, B. Hillebrands
The magnon gas created by spatially localized longitudinal parametric pumping in an yttrium-iron-garnet film is probed by a traveling packet of spin waves non-resonant with the pum…
Parametrically-stimulated recovery of a microwave signal using standing spin-wave modes of a magnetic film
A. V. Chumak, A. A. Serga, G. A. Melkov +3
The phenomenon of storage and parametrically-stimulated recovery of a microwave signal in a ferrite film has been studied both experimentally and theoretically. The microwave signa…
Formation of guided spin-wave bullets in ferrimagnetic film stripes
A. A. Serga, M. P. Kostylev, B. Hillebrands
The formation of quasi-2D nonlinear spin-wave eigenmodes in longitudinally magnetized stripes of a ferrimagnetic film, so-called guided spin-wave bullets, was experimentally observ…
Scattering of backward spin waves in a one-dimensional magnonic crystal
A. V. Chumak, M. P. Kostylev, A. A. Serga +1
Scattering of backward volume magnetostatic spin waves from a one-dimensional magnonic crystal, realized by a grating of shallow grooves etched into the surface of an yttrium-iron…
Phase reciprocity of spin-wave excitation by a microstrip antenna
T. Schneider, A. A. Serga, T. Neumann +2
Using space-, time- and phase-resolved Brillouin light scattering spectroscopy we investigate the difference in phase of the two counterpropagating spin waves excited by the same m…
