Oscillatory thickness dependence of the coercive field in three-dimensional anti-dot arrays from self-assembly

We present studies on magnetic anti-dot nano-structures with three-dimensional (3D) architectures, fabricated using a self-assembly template method. We find that patterning transverse to the film plane, which is a unique feature of this method, results in novel magnetic behavior. In particular, one of the key parameters for a magnetic material, the coercive field Bc, was found to demonstrate an oscillatory dependence on film thickness.

Abstract

We present studies on magnetic anti-dot nano-structures with three-dimensional (3D) architectures, fabricated using a self-assembly template method. We find that patterning transverse to the film plane, which is a unique feature of this method, results in novel magnetic behavior. In particular, one of the key parameters for a magnetic material, the coercive field Bc, was found to demonstrate an oscillatory dependence on film thickness.
