Fe 73.5 Cu 1 Nb 3 Si 13.5 B 9 非晶合金薄膜压磁效应的特征及负压磁效应(英文)
发布时间:2023-02-19 18:34
以Fe73.5Cu1Nb3Si13.5B9非晶合金薄膜作为研究对象,研究了其压磁效应的特征及其负压磁效应现象。结果表明,淬态下的Fe73.5Cu1Nb3Si13.5B9非晶合金薄膜在0~0.66 kPa压力带具有显著的正压磁效应,随着压应力增大,薄膜电感值下降。当压应力σ=0.66 kPa时,压磁效应值SI达到5.5%;环境温度对压磁效应灵敏度有影响,在20~30℃范围内,压磁效应和灵敏度稳定性最好,随着环境温度升高,薄膜灵敏度和压磁效应值均降低;薄膜经过退火处理后,薄膜内应力状态会发生变化,当退火温度≥350℃时,薄膜的压磁效应类型由"正压磁效应"转变为"负压磁效应",且随着薄膜中内应力降低,|SI|值下降,且薄膜的压磁效应受环境温度影响减小。当退火温度为555℃,σ=0.44 kPa时,|SI|值仅为0.59%;当退火温度达到薄膜的晶化温度时,薄膜的压磁效应受环境温...
