Template-Mediated Self-Assembly of Patterned Nanomagnets
We have introduced a new technique, template-mediated self-assembly (TMSA) to create ordered arrays of oriented hard magnetic clusters. The advantages of this novel technique over traditional self-assembly are that it can generate ordered cluster arrays up to centimeter scales or larger, and the magnetic dots can be aligned with a magnetic field. The figure shows an example of magnetic force microscopy (MFM) and atomic force microscopy (AFM) for a magnetic array of 50 nm FePt dots generated by TMSA. This technique has high potential for nanofabrication of arrays for high density magnetic recording or other nanodevices.
