"Effects of pining defects (PDs) on performance of magnetic recording reader are studied micromagnetically. The pinning defects could be present in antiferromagnet (AFM) and synthetic AFM," investigators in the United States report.
"Presence of pinning defects results in nonuniform pinned layer rotation at parallel (P) state as well as transfer curve (TC) artifacts at antiparallel (AP) state. The high field property, especially rolling off of TC in AP state, is also associated with different types of pinning defects," wrote L. Chen and colleagues.
The researchers concluded: "Time domain baseline popping noise as a result of PDs has been captured in ...
