“…In a NT, the lack of this axial Bloch point structure [8] is also expected to allow for fast magnetization reversal that begins with vortices nucleating at its ends and propagating along its length [9][10][11]. Due to their tubular geometry, NTs may reveal curvature-induced effects [12,13], such as asymmetric spin-wave dispersion [14] or Cherenkov-* martino.poggio@unibas.ch type emission of magnons by certain types of domain walls [15]. Theoretical studies of magnetization configurations in ferromagnetic NTs have predicted an equilibrium flux-closure configuration, the so-called global vortex state, as well as other configurations, including a uniform axial state and a mixed state [11].…”

“…This possibility may open up a direction to tailor the interfacial magnetic anisotropy in thin ferromagnetic films without any additional layers of heavy metal, which, in turn, may lead to simpler and cheaper ways to engineer systems with any given anisotropy. Nowadays, the curvature effects in thin magnetic films are becoming more accessible due to experimental advances in flexible electronics [23][24][25][26][27], making the proposed method to control the anisotropy experimentally viable in the near future. Moreover, our findings suggest that similar effects might be observed in thin films with significant surface roughness.…”

“…While the geometric influence on quantum transport of matter is becoming a hot topic in condensed matter, the topic of magnetism in curved geometry is evolving into an independent research field of modern magnetism with many exciting theoretical predictions and strong application potential [3,16]. Under the circumstances, the researching of the geometric influences on orbital * Email: wangyonglong@lyu.edu.cn † Email: zonghs@nju.edu.cn angular momentum (OAM) and on spin-orbit coupling (SOC) [17][18][19][20] becomes very necessary.…”
