摘要
We have produced magnetic patterns suitable for trapping and manipulating neutral atoms on a 1-mum length scale. The required patterns are made in Co/Pt thin films on a silicon substrate, using the heat from a focused laser beam to induce controlled domain reversal. In this way we draw lines and 'paint' shaped areas of reversed magnetisation with sub-micron resolution. These structures produce magnetic microtraps above the surface that are suitable for holding rubidium atoms with trap frequencies as high as similar to1 MHz.
