Abstract
In this paper the taper effect is discussed in various shielded spin valve
structures using the micro-magnetic modeling, It is found that long taper c
an result in the instability of sensor performance. In addition, it is hard
er to control the instability if sensors have more than three magnetic laye
rs because the demagnetizing fields become more complicated at sensor edges
with increasing magnetic layer number.
