Abstract In helimagnetic metals, ac current-driven spin motions can generate emergent electric fields acting on conduction electrons, leading to emergent electromagnetic induction (EEMI). Recent experiments reveal the EEMI signal generally shows a st

Abstract Two-dimensional skyrmion, a topological spin texture, has been extensively investigated in non-centrosymmetric magnets. It is thermodynamically stable in bulk materials and can extend perpendicularly to the spin-rotating plane, forming the t

Abstract In this study, our aim was to validate whether the automated measurement of salivary testosterone and cortisol concentrations and the testosterone-to-cortisol (T/C) ratio, considering their individual circadian rhythms can be used to assess

Nanometric topological spin textures, such as magnetic skyrmions (Sks) and antiskyrmions (antiSks), have attracted much attention in condensed matter physics and spintronics. To date, most studies have focused on two-dimensional Sks and antiSks in th

The three-dimensional (3D) topological spin textures – hopfions – were predicted in the helimagnetic systems but have not been experimentally confirmed thus far. This study utilized external magnetic field and electric current to realize 3D topol
