The rarely studied magnetic transition in phase‐change materials (PCMs) is discussed. The Fe₄₈Mo₁₄Cr₁₅C₁₅B₆Y₂ PCM with a novel magnetic transition is prepared. The experimental results indicate that the magnetic properties of the amorphous and crystalline phases of Fe₄₈Mo₁₄Cr₁₅C₁₅B₆Y₂ are significantly different. The amorphous film exhibits a spin‐glass behavior due to a disordered atomic arrangement, while the crystalline film exhibits a ferromagnetic behavior owing to its long‐range ferromagnetic interaction. The findings provide important insights into magnetic PCMs, which can contribute to the rapid development and application of magnetic‐transition‐based devices.

金属相变材料的磁跃迁

讨论了很少研究的相变材料（PCM）中的磁跃迁。制备了具有新型磁跃迁的Fe ₄₈ Mo ₁₄ Cr ₁₅ C ₁₅ B ₆ Y ₂ PCM。实验结果表明，Fe ₄₈ Mo ₁₄ Cr ₁₅ C ₁₅ B ₆ Y ₂的非晶相和结晶相的磁性能有很大的不同。由于无序的原子排列，非晶膜表现出自旋玻璃行为，而结晶膜由于其长距离的铁磁相互作用而表现出铁磁行为。这些发现提供了对磁性PCM的重要见解，可以为基于磁性过渡的设备的快速开发和应用做出贡献。
