Exploring the landscapes of Quasicrystal Artificial Spin Ices
Frank Barrows, Applied Physics Grad Student
By patterning materials into nanoscale networks the interplay between local energy terms can be manipulated and studied. In this way we can elucidate the competing interactions driving complex behavior. We are studying the influence that network geometry has on magnetic frustration in patterned magnetic films (Artificial Spin Ices). In this talk I will describe a novel analysis developed to characterize ordering in Quasicrystal Artificial Spin Ices. Additionally I will discuss the identification of local collective behavior based upon network connectivity in response to an applied magnetic field as well as the relationship between lattice frustration and emergent ordering.
