Recently, a skyrmion-tube mediated magnetization reversal process was theoretically reported in diameter modulated cylindrical nanowires where a vortex nucleates at the end of the segments with larger diameter and propagates, resulting in a first switching of the nanowire core magnetization at small fields. Here, we show experimental evidence of the so-called Bloch skyrmion-tubes, using advanced Magnetic Force Microscopy modes to image the magnetization reversal process of FeCoCu diameter modulated nanowires. By monitoring the magnetic state during applied field sweeping, a detected drop of magnetic signal at a given critical field unveils the presence of a skyrmion-tube, due to mutually compensating stray field components.<\/p>\n<p style=\"text-align: center\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-medium wp-image-2129\" src=\"https:\/\/wp.icmm.csic.es\/gnmp\/wp-content\/uploads\/sites\/10\/2021\/10\/octubre_2021_4-300x172.png\" alt=\"\" width=\"300\" height=\"172\" srcset=\"https:\/\/wp.icmm.csic.es\/gnmp\/wp-content\/uploads\/sites\/10\/2021\/10\/octubre_2021_4-300x172.png 300w, https:\/\/wp.icmm.csic.es\/gnmp\/wp-content\/uploads\/sites\/10\/2021\/10\/octubre_2021_4-1024x588.png 1024w, https:\/\/wp.icmm.csic.es\/gnmp\/wp-content\/uploads\/sites\/10\/2021\/10\/octubre_2021_4-768x441.png 768w, https:\/\/wp.icmm.csic.es\/gnmp\/wp-content\/uploads\/sites\/10\/2021\/10\/octubre_2021_4.png 1532w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/p>\n<p>This study is a collaboration between our GNMP group and the Institute of Nanotechnology, Karlsruhe Institute of Technology (KIT), Germany and the Departamento de F\u00edsica de la Materia Condensada and Condensed Matter Physics Center (IFIMAC), and the Instituto Nicol\u00e1s Cabrera, at the Universidad Aut\u00f3noma de Madrid.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>\u201cEvidence of Skyrmion-Tube Mediated Magnetization Reversal in Modulated Nanowires\u201d E.
