Abstract

Switching behavior and noise patterns due to an oblique misorientation of the easy axis of a system of noninteracting single domain particles (SDPs) has been investigated. Curvilinear nature of the head field as observed by the particle in the media has been taken into account using Monte Carlo simulation. For a heterogeneous media with a given set of half width of physical parameters in the distribution, one with an oblique misorientation angle near φ≃15⁰, appears to cause less fluctuation noise spikes and good readout signal. Media with a broad oblique misorientation distribution leads to a correspondingly broad transition width, rough switching curve and noisy signal output
