Peculiarities of the Faraday effect in gold-nanodisk/iron-garnet heterostructures

A. N. Kuzmichev, D. A. Sylgacheva, M. A. Kozhaev +10

In this paper, matters considering the immersion of gold nanoparticles inside a magnetic medium are investigated experimentally and theoretically. Three samples with periodic array…

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…

Exchange-torque-induced excitation of perpendicular standing spin waves in nanometer-thick YIG films

Huajun Qin, Sampo J. Hämäläinen, Sebastiaan van Dijken

Spin waves in ferrimagnetic yttrium iron garnet (YIG) films with ultralow magnetic damping are relevant for magnon-based spintronics and low-power wave-like computing. The excitati…

Temperature Dependence of Magnetic Excitations: Terahertz Magnons above the Curie Temperature

H. J. Qin, Kh. Zakeri, A. Ernst +1

When an ordered spin system of a given dimensionality undergoes a second order phase transition the dependence of the order parameter i.e. magnetization on temperature can be well-…
