Analysis of Magnetization Change with Temperature in an Artificial Spin Ice Network by Three Dimensional Finite Element Modeling

A three dimensional finite element model calculation was constructed, which includes different submodels, all as a function of temperature, using an iterative approach, to investigate permalloy artificial spin ice network with square geometry on thermal annealing while applying voltage pulse. Magnetization is also included into the simulation equation defining change magnetization temperature. The maximum temperature obtained around sharp corners due current crowding, and therefore, minimum values are observed same place, even zero depending applied pulse magnitude width, because Curie permalloy. aim this study understand dynamic behavior according programming importance device design minimize effect joule heating.
