Here we demonstrate electric-field control of ferromagnetism in a thin-film ... Magnetic-field dependence of the sheet Hall resistance R Hall proportional to the magnetization of the magnetic ...

As they changed the strength of the electric field that they applied to the material, they found several settings where resistance vanished. In two cases, the superconductivity flickered, with ...

In 2004, after decades of trying, physicists managed to isolate a sheet of graphene — a hexagonal lattice of carbon atoms — using a novel exfoliation procedure: They used Scotch tape to peel the sheet ...
