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。
