Abstract: A research was conducted with an aim to correlate the magnetic properties of CoFeB trilayer thin films with the impedance responses and to investigate the potential use of this material for magnetoimpedance (MI) sensor applications. The MI effect of the 50/100/50-nm trilayer was improved after field annealing, exhibiting a maximum of up to 9% in a 20-mum-wide meander.
