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…

Analysis of spectral modification of mesons at finite density using a transport approach in the 12 GeV pA reactions
PS E325 Collaboration, Masaya Ichikawa, Philipp Gubler +26
The hadron spectrum at finite density is an important observable for exploring the origin of hadron masses. In the KEK-PS E325 experiment, the di-electron decays of phi mesons insi…
