Identifying reversible and irreversible magnetization changes in prototype patterned media using first- and second-order reversal curves

Winklhofer, Michael, Randy K. Dumas, and Kai Liu (2008), Identifying reversible and irreversible magnetization changes in prototype patterned media using first- and second-order reversal curves, J. Appl. Phys., 103(7), 07C518, doi:10.1063/1.2837888.

Abstract
Arrays of nanomagnets have important potential applications as future generation ultrahigh-density
patterned magnetic recording media, in which each nanomagnet constitutes a single bit. We introduce
a powerful technique to identify and quantify reversible and irreversible magnetization changes,
a key challenge in characterizing these systems. The experimental protocol consists of measuring a
few families of second-order reversal curves along selected profiles in the first-order-reversal-curve
diagram, which then can be decomposed into truly irreversible switching events and reversible magnetization
changes. The viability of the method is demonstrated for arrays of sub-100 nm Fe nanomagnets,
which exhibit complex magnetization reversal processes.
