We present an analysis and comparison of magnetization and remanence data from two particulate systems: commercial CrO/sub 2/ audiotape and a frozen suspension of magnetoferritin particles. The measurements were performed over a range of temperatures

The magnetization reversal of chains of 40–50 nanometer, magnetic particles has been studied using Magnetic Force Microscopy (MFM) in an applied field. The field was stepwise increased and decreased in order to make hysteresis loops for the chains.

The magnetization reversal in epitaxial iron 〈1 1 1〉 films has been studied using MFM with in situ magnetic fields and, in addition, correlated with macroscopic data obtained by conventional magnetometry. Due to the crystallographic orientation a

The effect of finite temperature T and observation time t on the Henkel plots of ac and thermally demagnetized systems has been investigated within the framework of a generalized Preisach model, in which it is assumed that thermally activated hopping

The implications of thermal demagnetization with respect to the observation of interaction effects in Henkel plots are discussed within the framework of a scalar moving Preisach model. The Preisach distribution is assumed to be a product of a Gaussia

Magnetic force microscope (MFM) images of various domain wall structures will be discussed. The systems studied in this work include single crystals of magnetite (Fe/sub 3/O/sub 4/) and a 0.5 /spl mu/m single crystal iron (Fe) film. In general, the o

The magnetic reversal mechanism of tapered permalloy bars with holes in the center was studied using a Magnetic Force Microscope with in situ magnetic field capability. The samples studied were lithographically patterned from a 20-nm-thick NiFe film
