A typical magnet contains a host of tiny "magnetic moments" that are locked into alignment with other magnetic moments, all acting in unison to create a magnetic field. Exposing this assembly to heat will eliminate the magnetism; these little moments will remain—but they'll be pointing in ran...
the first column shows the demagnetized state of a multilayer material containing gadolinium and cobalt; the second column shows the residual magnetism in the same samples after an external, positive magnetic field was applied and then removed; and the last column shows the samples when a negative...
"In the past, everyone thought that magnetism andsuperconductivitycould not coexist," said ORNL's Claudia Cantoni, the study's first author. "The whole idea of superconductors is that they expel magnetic fields. But in reality things are more complicated." Superconductivity is strongly suppressed b...

"Sometimes you are handed surprises like this," Prakapenka said. Superionic ice doesn't exist only inside far-away planets — it's also inside Earth, and it plays a role in maintaining our planet's magnetic fields. Earth's intense magnetism protects the planet's surface from dangerous radi...
