The first measurements of magnetic excitations rippling through a nickelate (Ni) superconductor show it's closely related to cuprate (Cu) superconductors, which conduct electricity with no loss at relatively warm temperatures. The study by researchers at SLAC, Stanford and Diamond Light Source revealed important similarities and subtle differences between the two materials.
