Perpendicular magnetic anisotropy tuning of macrospin-to-vortex transitions in Co-based artificial spin-vortex ice
Yu Maruyama, Amrit Kumar Mondal, Bijaya Kharel +4
We investigate the macrospin-to-vortex (MS-to-V) transition in Co-based artificial spin-vortex ice (ASVI) in the presence of perpendicular magnetic anisotropy (PMA) by spin-wave sp…
Type-II-like ultrafast demagnetization behavior in NiCo2O4 thin films
Ryunosuke Takahashi, Kaede Yamada, Harjinder Singh +10
Rare-earth-ferrimagnetic oxides are emerging as attractive platforms for investigating ultrafast spin dynamics. Here, we study the photoinduced magnetization dynamics of epitaxial…
NasoVoce: A Nose-Mounted Low-Audibility Speech Interface for Always-Available Speech Interaction
Jun Rekimoto, Yu Nishimura, Bojian Yang
Silent and whispered speech offer promise for always-available voice interaction with AI, yet existing methods struggle to balance vocabulary size, wearability, silence, and noise…
Observation of the crossover from quantum fluxoid to half-quantum fluxoid in a chiral superconducting device
Masashi Tokuda, Fumiya Matsumoto, Noriaki Maeda +16
Topological superconductors are one of the intriguing material groups from the viewpoint of not only condensed matter physics but also industrial application such as quantum comput…
Enhancement of spin-wave nonreciprocity and group velocity in a low-wavenumber regime
Shion Yoshimura, Shugo Yoshii, Ryo Ohshima +1
Nonreciprocity of spin waves is essential for components such as magnetic isolators and circulators used in spin-wave-based computing. A ferromagnetic (FM) bilayer exhibits signifi…
Anomalous Nernst effect in Co thin films under laser irradiation
Soichiro Mochizuki, Itaru Sugiura, Tetsuya Narushima +3
The anomalous Nernst effect (ANE) generates electromotive forces transverse to temperature gradients and has attracted much attention for potential applications into alternative th…
