Effects of layer thickness and annealing process on low-frequency noise and detectivity in tunnel magnetoresistive sensors with CoFeSiB soft magnetic layers

We investigated the effects of CoFeSiB soft magnetic layer thickness and annealing process on the magnetic field sensing and low-frequency 1/f noise characteristics of tunnel magnetoresistive (TMR) sensors. A thicker CoFeSiB layer improved the soft magnetic properties of the free layer, and the proc...
