Propagating spin waves in nanometer-thick yttrium iron garnet films: Dependence on wave vector, magnetic field strength and angle
Huajun Qin, Sampo J. Hämäläinen, Kristian Arjas +2
We present a comprehensive investigation of propagating spin waves in nanometer-thick yttrium iron garnet (YIG) films. We use broadband spin-wave spectroscopy with integrated copla…
Programmable control of spin-wave transmission in a domain-wall spin valve
Sampo J. Hämäläinen, Marco Madami, Huajun Qin +2
Active manipulation of spin waves is essential for the development of magnon-based technologies. Here, we demonstrate programmable spin-wave filtering by resetting the spin structu…
Static properties and current-induced dynamics of pinned degree magnetic domain walls under applied fields: an analytic approach
Pavel Baláž, Sampo J. Hämäläinen, Sebastiaan van Dijken
Magnetic domain walls are pinned strongly by abrupt changes in magnetic anisotropy. When driven into oscillation by a spin-polarized current, locally pinned domain walls can be exp…
