Materials with unprecedented and exotic properties are crucial for addressing energy and environmental crisis. However, many existing materials are approaching performance limits due to inherent physical constraints. Here, we report a multi-level ordered structure (MOS) strategy to address these challenges. Using magnetic material as a proof of concept, we demonstrate a resistive magnetic metal with high thermal stability, which is challenging due to the abundant free electrons in metals and inherent instability of the magnetized state, but highly sought after for future high-frequency and high-power applications. The obtained MOS material features multiple ordered characteristics across different levels, exhibiting large electrical resistivity surpassing its constituents by 2600%, while achieving an over 100% improvement in magnetic thermal stability that outperforms state-of-the-art commercial counterparts. Furthermore, it also achieves enhancements in coercivity, corrosion resistance and stiffness. The MOS strategy manipulates functional processes to simultaneously overcome multiple physical constraints and transcend performance bottlenecks.
具有前所未有的奇异特性的材料对于应对能源和环境危机至关重要。然而，由于固有的物理限制，许多现有材料正接近性能极限。在此，我们报告一种多级有序结构（MOS）策略来应对这些挑战。以磁性材料作为概念验证，我们展示了一种具有高热稳定性的电阻磁性金属，由于金属中丰富的自由电子和磁化状态固有的不稳定性，这极具挑战性，但对于未来的高频和高功率应用却备受追捧。所获得的MOS材料在不同层次上具有多种有序特性，表现出大幅超过其组分2600%的高电阻率，同时实现了超过100%的磁热稳定性提升，优于最先进的商业同类产品。此外，它还在矫顽力、耐腐蚀性和硬度方面实现了增强。MOS策略操控功能过程以同时克服多种物理限制并突破性能瓶颈。
