Abstract
The baseline shift in a micro-track profile of spin valve heads was investigated. Experimental and micro-magnetic modeling results were compared and found in close agreement. It was confirmed that the nonuniformity of pinning field and variation of anisotropy were among the potential sources of the formation of multi-states and the baseline instability. It was shown that the resulting instability could be suppressed by applying a strong permanent magnet stabilization field
