Topological frustration of artificial spin ice [PDF]
Nature Communications, 2017 Frustrated systems display rich behaviour due to unsatisfied competing interactions. Here, the authors report extended frustration by introducing controlled topological defects into square artificial spin ice lattices, demonstrating the potential of ...

String Phase in an Artificial Spin Ice [PDF]
Nature Communications, 2021 Strings of local excitations are interesting features of a strongly correlated topological quantum matter. Here, the authors show that Boltzmann-distributed strings of local excitations also describe the topological physics of the Santa Fe geometry of ...

Clocked dynamics in artificial spin ice [PDF]
Nature CommunicationsArtificial spin ice (ASI) are nanomagnetic metamaterials with a wide range of emergent properties. Through local interactions, the magnetization of the nanomagnets self-organize into extended magnetic domains.

Artificial spin ice phase-change memory resistors [PDF]
New Journal of Physics, 2022 We present a proposal for realization of an electrical memory reminiscent of a memristor in connected Kagome artificial spin ice. We show that current flowing through the system alters the magnetic ensemble, which in turns controls the overall resistance

Nonlinear multi-magnon scattering in artificial spin ice [PDF]
Nature Communications, 2023 Magnons, the quantum-mechanical fundamental excitations of magnetic solids, are bosons whose number does not need to be conserved in scattering processes.

Observation of Coherent Spin Waves in a Three-Dimensional Artificial Spin Ice Structure [PDF]
Nano Letters, 2021 Harnessing high-frequency spin dynamics in three-dimensional (3D) nanostructures may lead to paradigm-shifting, next generation devices including high density spintronics and neuromorphic systems. Despite remarkable progress in fabrication, the measurement and interpretation of spin dynamics in complex 3D structures remain exceptionally challenging ...

Defect-induced monopole injection and manipulation in artificial spin ice [PDF]
Nature Communications, 2022 Artificial spin ice systems offer a promising platform to study the motion of emergent magnetic monopoles, but controlled nucleation of monopoles is challenging.

Magnetic charge propagation upon a 3D artificial spin-ice [PDF]
Nature Communications, 2021 Two-dimensional artificial spin-ice systems have been studied for over 15 years but do not capture the detailed geometry of their bulk counterparts. Here, the authors fabricate a three-dimensional artificial spin-ice and show that the surface termination

Understanding thermal annealing of artificial spin ice [PDF]
APL Materials, 2019 We have performed a detailed study on thermal annealing of the moment configuration in artificial spin ice. Permalloy (Ni80Fe20) artificial spin ice samples were examined in the prototypical square ice geometry, studying annealing as a function of island
