- Abstract
- We report our systematic investigation of temperature-dependent Barkhausen volume behavior for CoFeB/Pd with perpendicular magnetic anisotropy by means of magneto-optical Kerr microscopy. In the temperature range where two-dimensional (2D) Ising-like and single-domain features are sustained, hysteresis parameters such as coercivity, hysteresis area, and saturation magnetization are quantitatively analyzed with respect to the temperature. Interestingly it is demonstrated that the Barkhausen length is directly proportional to the domain-wall width via the magnetic anisotropy in this single-domain and 2D Ising-like model system. © 2024 American Physical Society.
