... to sense the stress, it can be easily interfered by environment. In this paper, a new MBN sensor is fabricated by selecting FeCoNi(AlMn) 0.25 high entropy alloy (HEA) as the case of magnetic core to improve the accuracy of stress evaluation. The process optimization results show that the stability of MBN...
