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…

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…
