"signal is at a single momentum point, and second is that the signal is at a low frequency. A single momentum low frequency excitation means there's a long-lived excitation that helps the researchers see and describe the system... antiferromagnetic fluctuations—when electrons spin in the opposite direction—accounted for a majority of the superconductivity... ferromagnetic fluctuations that counteracted the antiferromagnetic fluctuations, which ultimately brought them back to the 50% finding"
