我们展示了无序系统的结构、磁输运和磁性能的实验研究结果，该无序系统由嵌入 B-Al-O 氧化物基体中的尺寸为 2-5 nm 的应变晶体 CoFe 纳米颗粒组成，并具有大量分散的 Fe 或 Co 原子。它们在基质中充当磁性离子，对 T 时的磁化强度有重要贡献
We present results of an experimental study of structural, magnetotransport, and magnetic properties of a disordered system which consists of the strained crystalline CoFe nanogranules with the size of 2-5 nm embedded into the B-Al-O oxide matrix with a large number of dispersed Fe or Co atoms. They act in the matrix as magnetic ions and contribute essentially to the magnetization at T
