Wideband Brillouin light scattering analysis of spin waves excited by a white-noise RF generator
Lukáš Flajšman, Ondřej Wojewoda, Huajun Qin +3
Spin waves are studied intensively for their intriguing properties and potential use in future technology platforms for the transfer and processing of information and microwave sig…
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-…
Direct Determination of Electron-Phonon Coupling Matrix Element in a Correlated System
Huajun Qin, Junren Shi, Yanwei Cao +7
High-resolution electron energy loss spectroscopy measurements have been carried out on an optimally doped cuprate Bi2Sr2CaCu2O8+δ. The momentum-dependent linewidth and the dispers…
Quintuple-layer epitaxy of high-quality Bi2Se3 thin films for topological insulator
Guanhua Zhang, Huajun Qin, Jing Teng +5
We report the growth of atomically smooth, single crystalline Bi2Se3 thin films on Si(111) by using molecular beam epitaxy. Scanning tunneling microscopy, low-energy electron diffr…
