Micromagnetic Investigation of Periodic Cross-Tie/Vortex Wall Geometry

Figure 4

Average total energy density as a function of period length 𝑋 for simulations with width 𝑌=200ℓ_ex for various thicknesses 𝑍 (measured in ℓ_ex). Symbols represent simulation results, lines are a guide to the eye. Each of the curves with 𝑍≥2ℓ_ex exhibits a minimum value between 125ℓ_ex and 320ℓ_ex. In this range, the curves for 𝑍≤1ℓ_ex are monotonically decreasing with 𝑋.
