In direct-write atom lithography, also known as laser-focused deposition, atoms are focused into a periodic pattern by a standing light wave and deposited on a substrate. The basis of this technology is the dipolar interaction of near resonant light with neutral atoms. As the dipolar force is weak compared to the electric or magnetic force used to focus charged articles, atom lithography was assumed to work only for laser cooled atom beams. We have shown that it is possible to do atom lithography with thermal beams of Fe atoms without laser cooling if the geometry of the setup is chosen well, creating geometric cooling effects [1]. We will discuss the effects of geometric cooling on the focusing process. [2] We will also present the magnetic properties of Fe layers that are structured using atom lithography in nanoline arrays on a Fe background. We find unusual biaxial anisotropic magnetic properties in these line arrays.
