Micromagnetics: read head or read sensor; Magnetoresistance
Practical methods for micromagnetic modeling of broadband magnetic thermal. fluctuation noise in magnetoresistive CPP read sensors/heads are described using a matrix form of the linearized Gilbert equations. The scaling of magnetic signal/noise vs. device size and geometry is considered in detail, as are the individual normal-mode. fluctuations of free and reference layers. Natural-mode stability analysis methods for spin-torque effects is also briefly considered. (C) 2008 Elsevier B.V. All rights reserved.
