Echo state property and memory capacity of artificial spin ice [PDF]
Scientific ReportsPhysical reservoir computing by using artificial spin ice (ASI) has been proposed on the basis of both numerical and experimental analyses. ASI is a many-body system consisting of ferromagnets with various interactions.

Dynamics and hysteresis in square lattice artificial spin ice
New Journal of Physics, 2013 Dynamical effects under geometrical frustration are considered in a model for artificial spin ice on a square lattice in two dimensions. Each island of the spin ice has a three-component Heisenberg-like dipole moment subject to shape anisotropies that ...

Reservoir Computing in Artificial Spin Ice [PDF]
The 2020 Conference on Artificial Life, 2020 Artificial spin ice (ASI) are systems of coupled nanomagnets arranged on a 2D lattice. ASIs are promising computing substrates due to the rich variety of emergent behavior, accompanied by considera...

Advances in artificial spin ice [PDF]
Nature Reviews Physics, 2019 Artificial spin ices consist of nanomagnets arranged on the sites of various periodic and aperiodic lattices. They have enabled the experimental investigation of a variety of fascinating phenomena such as frustration, emergent magnetic monopoles and phase transitions that have previously been the domain of bulk spin crystals and theory, as we discuss ...

Field‐Driven Reversal Models in Artificial Spin Ice [PDF]
Advanced Theory and Simulations, 2021 AbstractA set of topological arrangements of individual ferromagnetic islands in ideal and disordered artificial spin ice (ASI) arrays is investigated in order to evaluate how aspects of their field‐driven reversal are affected by the model used. The set contains the pinwheel and square ice tilings, and thus a range of magnetic ordering and reversal ...

Experimental Observation of Magnetic Monopoles in Spin Ice
, 2021 In spin ice, the model of magnetic monopoles arises as a transformation of the dipolar spin ice Hamiltonian developed for materials such as Dy2Ti2O7 and Ho2Ti2O7.

Exploring the phase diagram of 3D artificial spin-ice
Communications Physics, 2023 Artificial spin-ices consist of lithographic arrays of single-domain magnetic nanowires organised into frustrated lattices. These geometries are usually two-dimensional, allowing a direct exploration of physics associated with frustration, topology and ...
