Abstract In the present paper we report on the magnetic properties of the (Fe0.7Co0.3)83.7Si4B8P3.6Cu0.7 ribbons produced by melt spinning and microwires prepared using Taylor-Ulitovsky technique. Depending on the cooling rate the ribbon samples have either an amorphous or partly crystalline structure. Excellent magnetic softness with coercivity of about 5 A/m and high saturation magnetization of about 1.87 T was found in the partly crystalline state ribbon. Glass–coated (Fe0.7Co0.3)83.7Si4B8P3.6Cu0.7 microwires with a mixed amorphous/nanocrystalline structure exhibit perfectly rectangular hysteresis loops and unusually high domain wall mobility that must be associated to elevated saturation magnetization values.

(Fe0.7Co0.3)83.7Si4B8P3.6Cu0.7带材和微丝的优异磁性能

摘要 在本文中，我们报告了通过熔体纺丝和使用 Taylor-Ulitovsky 技术制备的微丝生产的 (Fe0.7Co0.3)83.7Si4B8P3.6Cu0.7 带材的磁性能。根据冷却速度，带样品具有非晶态或部分晶体结构。在部分结晶状态的薄带中发现具有约 5 A/m 的矫顽力和约 1.87 T 的高饱和磁化强度的优异磁软性。具有混合非晶/纳米晶结构的玻璃涂层 (Fe0.7Co0.3)83.7Si4B8P3.6Cu0.7 微线表现出完美的矩形磁滞回线和异常高的畴壁迁移率，这必须与升高的饱和磁化强度值相关。
