DESCRIPTION:Artificial spin ice (ASI) is a highly customizable materials pl
 atform used for studying fundamental properties of interaction and frustra
 tion in magnetic systems\, with potential applications in novel computing 
 architectures. Perpendicular ASI systems are advantageous because they hav
 e isotropic interactions between magnetic elements and high perpendicular 
 stray fields that could be used for magnetic imprinting. These perpendicul
 ar systems can be studied using magneto-optical Kerr effect microscopy\, a
 llowing for complete microstate mapping in situ with an applied field. The
 y can also be modeled using micromagnetic simulations to provide a more de
 tailed analysis of the magnetic state of the elements. We are currently in
 terested in characterizing modifications to perpendicular ASI in the form 
 of connections between neighboring elements and soft magnetic underlayers.
  These modifications will allow us to selectively control the final state 
 of the array after demagnetization and could aid in functionalizing these 
 systems for future technological applications. I will present on simulatio
 ns and initial results on fabricated samples.\n\nWork performed at the Cen
