Inverse-design of two-dimensional magnonic crystals via topology optimization with frequency-domain micromagnetics
Ryunosuke Nagaoka, Takahiro Yamazaki, Chiharu Mitsumata +2
Magnonic crystals (MCs) are emerging spintronic metamaterials capable of manipulating transmission properties of magnons, the quanta of spin waves. Due to the complex relationship…
X-ray detected ferromagnetic resonance spectrometer with an out-of-vacuum photodetector
Tetsuro Ueno, Yasuo Takeichi, Masaki Mizuguchi +10
X-ray detected ferromagnetic resonance (XFMR) spectroscopy is an experimental technique for element-specific spin dynamics in the GHz regime and has been utilized to study spintron…
Persistent Homology-Based Indicator of Orientational Ordering in Two-Dimensional Quasi-Particle Systems Applied to Skyrmion Lattices
Michiki Taniwaki, Thomas Brian Winkler, Jan Rothörl +4
Two-dimensional (2D) particle systems, such as magnetic skyrmions, exhibit topological phase transitions between unique 2D phases. However, a simple and computationally efficient m…
Efficient stopping of current-driven domain wall using a local Rashba field
Gen Tatara, Henri Saarikoski, Chiharu Mitsumata
We theoretically show that a locally-embedded Rashba interaction acts as a strong pinning center for current-driven domain walls and demonstrate efficient capturing and depinning o…
Effect of Spin Torque on Magnetization Switching Speed Having Nonuniform Spin Distribution
Kazushige Hyodo, Chiharu Mitsumata, Akimasa Sakuma
We study the influence of the spin torque, which depends on the space and time derivative of magnetization, on magnetization reversal time in a ferromagnetic fine particle. The spi…
