Created a note titled “From Classical Heisenberg Model to Spiral Magnetism”, which guides readers through using the classical Heisenberg model to determine the conditions under which spiral magnetic configuration emerges. Available in both the Chinese version “从古典海森堡模型到螺旋磁性” and the Japanese version “古典 Heisenberg 模型から螺旋磁性へ”. An English version is not yet available.
