Freshly published in Advanced Materials: A nano-Galton Board based on Artificial Spin Network !
In this work, the motion of the magnetic domain walls in an artificial spin lattice leads to a tunable stochastic response of the metamaterial, which can be tailored by an external magnetic field and local lattice modifications. This type of stochastic tunable lattice produces a controllable random response exploiting the intrinsic stochasticity of the magnetic domain wall motion at the nanoscale.
This nice move results from a collaboration between IJL , UmPhy CNRS-Thales, C2N et Institut Néel in the ANR Bio-Ice framework coordinated by Dr. D. Lacour.
