A flower-shaped structure only a few micrometers in size made of a nickel-iron alloy can concentrate and locally enhance ...

However, due to the presence of strong magnetic fields, the electron energies become confined into discrete energy levels. This process dramatically enhances the interaction between the electrons ...

A flower-shaped structure only a few micrometres in size made of a nickel-iron alloy can concentrate and locally enhance magnetic fields. The size of the effect can be controlled by varying the ...
