Researchers have demonstrated that phosphorene nanoribbons (PNRs) exhibit both magnetic and semiconducting properties at room temperature. The research establishes PNRs as a unique class of ...

This can be "seen" in two dimensions if iron filings are sprinkled ... efficient if the coil was wound around a metal core, as this helped to concentrate the magnetic field.

A 1/2 inch diameter cylindrical magnet works well. Iron Filings: Available from: Science supply stores like Home Science Tools, Carolina Biological, or Educational Innovations Some craft stores in ...

Room-temperature magnetic and electronic traits make phosphorene nanoribbons promising for next-gen, energy-efficient nanoelectronics.
