The magnetostatic interaction between two oppositely charged transverse domain walls (TDWs) in adjacent Permalloy nanowires is experimentally demonstrated. The dependence of the pinning strength on wire separation is investigated for distances between 13 and 125 nm. The results can be described fully by considering the distribution of magnetic charge within rigid, isolated TDWs. Alternative DW ...

The paper is devoted to the development of Hall thruster plasma non-contact magnetic diagnostics methods applicable for onboard diagnostics system. The approach to Hall current structure determination using steady-state magnetic measurements proposed in our previous work is further developed. The approach is based on inverse magnetostatic problem solution using two-dimensional constrained regul...

The bottleneck of micromagnetic simulations is the computation of the long-ranged magnetostatic fields. This can be tackled on regular N-node grids with Fast Fourier Transforms in time N logN , whereas the geometrically more versatile finite element methods (FEM) are bounded to N in the best case. We report the implementation of a Non-uniform Fast Fourier Transform algorithm which brings a N lo...

Cylindrical ferromagnetic nanowires are of particular interest in nanomaterials science due to various manufacturing methods and a wide range applications nanotechnology, with special attention given those diameters less than the single domain limit. In current study, simulations magnetic properties isolated iron diameter 5 nm aspect ratios, as well two types arrays such (with hexagonal square ...
