磁性结构预测长期依赖昂贵实验或复杂第一性原理计算，MSN用图神经网络直接预测，精度接近实验，做磁性材料或凝聚态物理的团队值得关注，可以大幅加速筛选流程。
研究人员提出了磁性结构网络（MSN），这是一种E(3)等变图神经网络，能够直接从原子晶体结构预测共线和非共线磁性结构。该模型基于MAGNDATA实验数据训练，并引入原始调制结构表示（PMSR），统一编码了共度和非共度磁性结构，无需对称性假设。MSN在所有调制分量上表现优异，能够高保真地重建实验磁性结构。该方法为快速磁性结构预测提供了可扩展框架，有望推动数据驱动的磁性材料发现。
Universal Magnetic Structure Prediction from Atomic Coordinates with Near-Experimental Accuracy
Magnetic order is a fundamental property of materials, governing collective behavior and enabling a broad range of functionalities. Yet magnetic structure remains difficult to determine: experiments are costly and specialized, while first-principles methods often struggle with the noncollinear and incommensurate orders found in real materials. Here we introduce magnetic structure network (MSN), an E(3) equivariant graph neural network that predicts both collinear and non-collinear magnetic structures directly from atomic crystal structures, trained directly on experimentally determined structures from MAGNDATA. By proposing the primitive modulated structure representation (PMSR), we are able to encode commensurate and incommensurate structures in a unified way without symmetry assumptions. The model achieves strong performance across all modulation components and reconstructs experimental magnetic structures with high fidelity. Our approach provides a scalable framework for rapid magnetic structure prediction and opens a route to data-driven discovery of magnetic materials.
