Influence of Switching Field Distribution on the Transition Jitter in Grain-Position Controlled Granular Media

抄録

  Jitter noise reduction can be achieved by controlling the position of magnetic grains. We have shown that position controlled granular media can suppress jitter noise. In this paper, the influence of grain alignment on square and triangular lattices and the switching field distribution on the jitter noise was calculated with a Voronoi cell model. The switching field distribution was found to have a significant effect and depended on the down-track distance between grains.
