Unhappy Vertices in Artificial Spin Ice: Degeneracy from Vertex-Frustration
Muir J. Morrison, Tammie R. Nelson, Cristiano Nisoli
In 1935, Pauling estimated the residual entropy of water ice with remarkable accuracy by considering the degeneracy of the ice rule {\it solely at the vertex level}. Indeed, his es…
Degeneracy and criticality from emergent frustration in artificial spin ice
Gia-Wei Chern, Muir J. Morrison, Cristiano Nisoli
Although initially introduced to mimic the spin-ice pyrochlores, no artificial spin ice has yet exhibited the expected degenerate ice-phase with critical correlations similar to th…
Perpendicular Magnetization and Generic Realization of the Ising Model in Artificial Spin Ice
Sheng Zhang, Jie Li, Ian Gilbert +11
We have studied frustrated kagome arrays and unfrustrated honeycomb arrays of magnetostatically-interacting single-domain ferromagnetic islands with magnetization normal to the pla…
Direct entropy determination and application to artificial spin ice
Paul E. Lammert, Xianglin Ki, Jie Li +4
From thermodynamic origins, the concept of entropy has expanded to a range of statistical measures of uncertainty, which may still be thermodynamically significant. However, labora…
On thermalization of magnetic nano-arrays at fabrication
Cristiano Nisoli
We propose a model to predict and control the statistical ensemble of magnetic degrees of freedom in Artificial Spin Ice (ASI) during thermalized adiabatic growth. We predict that…
