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-…
