Maximum steel magnetization (near saturation) could be obtained if the rings were stacked to make a roll using a 4:1 ratio of magnet to steel thickness, see Figure 1. Since magnetized particles are attracted to the magnetized steel surface on the roll periphery, this means that 20% of the exposed roll surface would collect such material.

Jun 03, 2008 We extend our earlier treatment of two magnon scattering in ultrathin ferromagnets to the case where the magnetization is tipped out of plane by virtue of the application of an out of plane magnetic field. The general formalism developed earlier is generalized in this regard, so when the magnetization is canted out of plane, one may extract information on the two magnon contribution to …
