Tuning domain wall oscillation frequency in bent nanowires through a mechanical analogy

“…Current fabrication techniques at the nanoscale allow the preparation of NWs with well-controlled shapes and sizes [17][18][19][20][21][22][23][24][25][26]. Particularly, advances in 3D-printing techniques [27,28] have enhanced the fabrication of multifaceted [29] and curved [30][31][32] magnetic NWs.…”

“…p = +1 (p = −1) corresponds to a head-to-head (tailto-tail) DW. In our calculations, we analyze cases where κλ < 1, which allows us to consider λ as a slave dynamical variable presenting very small deformations [24,59] so that a rigid DW model can be adopted. This constraint also ensures the validity of the ansatz, whose plausibility for the case κλ > 1 is not well established [36].…”
