我们突破微扰框架,建立半填充二分网络中磁交换规则的非微扰推广。历史模型严格局限于稀溶液极限下有争议的微扰方法,且要求无零能模,而我们的通用机制可支配任意二分图的交换相互作用。该框架绕过传统展开瓶颈,为复杂晶格的磁性提供分析预测工具,为下一代二维自旋电子器件设计稳定长程有序结构提供关键设计准则。
英文摘要
We break from perturbative frameworks to establish a non-perturbative generalization of magnetic exchange rules in half-filled bipartite networks. While historical models remain strictly tied to the debatable perturbation approach in the dilute limit and require the absence of zero-energy modes, our universal mechanism governs exchange interactions across arbitrary bipartite graphs. By bypassing traditional expansion bottlenecks, this framework provides an analytical predictive tool for magnetism in complex lattices, offering key design principles to engineer stable, long-range order in next-generation 2D spintronic devices
