Combining Titanium and Gold to make 1st itinerant antiferromagnet: TiAu. This is not the kind of magnet one would stick to a refrigerator. Magnetic order only appears in TiAu when the metal is cooled to 36K = -395F. “Magnetization is a function of temperature,” said lead author Eteri Svanidze. “The magnet’s ordering temperature appears as an anomaly in the smooth curve we see in such magnetization measurements.” For common magnets, it is generally 100s of degs F, way hotter than any kitchen...
