Tunable superconducting devices with a reconfigurable artificial-spin-ice

ORAL

Abstract

Recent work has shown that the magnetic charges in an artificial spin ice can strongly influence the properties of materials in contact with the spin ice structure [Science 352, 962 (2016) & Nature Nano. 13, 560 (2018)]. Here, we present a novel heterostructure combining a newly-introduced artificial spin ice pattern with a superconducting MoGe film. The reconfigurable magnetic template produced by artificial spin ice strongly couples with the vortices in the superconducting film, which enables us to control its transport properties. We will demonstrate some tunable functions of this artificial-spin-ice and superconductor heterostructure.
