Slide words: Spin density contours in two planes perpendicular to the c axis of of Mn5Ge where the solid (dashed) lines denote positive (negative) spin density.

Slide Image: Two images showing symmetrical patterns formed by spin density contours in two planes. This is an illustration that depicts a new field called "spintronics," a nanotechnology field. "Spintronics" is short for "Spin Based Electronics" and seeks to exploit the possibility that the electron's spin--in addition to its charge--can be applied to process and store information. The solid lines show positive spin density in a manganese-germanium compound and the dashed lines denote negative spin density.
