摘要 | The structure symmetry in artificial spin ice systems plays important roles in the magnetization reversal process when subjected to an external magnetic field. We investigated the magnetization reversal processes with different field orientations in the deformed kagome spin ices with threefold symmetry broken using high-resolution Kerr microscopy. Distinct magnetization reversal processes were observed in the deformed kagome system when compared to those found in standard kagome structures. In addition to the previously documented Dirac-string-like and system-size avalanche-type reversals, we identified two unusual reversal behaviors: the armchairlike avalanche and the discrete magnetization reversal within a single bar. These behaviors can be elucidated through the modified energy hierarchy present in the deformed kagome spin ices. Furthermore, we observed that the magnetization reversal behaviors in deformed kagome ice can be manipulated by selecting different initial spin states. These findings contribute to a deeper comprehension of nonequilibrium critical point phenomena in artificial spin ice systems. © 2024 American Physical Society. |
