摘要：
Microstructure and magnetic properties are studied for Fe78Co5Zr6Ge5B5CU1 alloy. Curie temperature of the amorphous phase is increased by 200 K with respect to Fe-Zr-B-Ge-Cu alloys, without losing the ultrasoft magnetic properties exhibited at room temperature (Hc similar to 10 A/m). Nanocrystalline microstructure shows a high crystalline volume fraction of alpha-Fe nanocrystals (similar to 0.85) with size below 13 nm. Ge content in the crystalline phase is found to decrease continuously during nanocrystallization. (c) 2004 Elsevier B.V. All rights reserved.
