The Curie temperature is named after Pierre Curie, who showed that magnetism was lost at a critical temperature. In its pure form, neodymium has magnetic properties—specifically, it is antiferromagnetic—but only at low temperatures, below 19 K (−254.2 °C; −425.5 °F). But some compounds of neodymium with transition metals such as iron are ferromagnetic, with Curie temperatures well above room temperature. These are used to make neodymium magnets. The strength of neodymium magnets is the result of several factors. The most important is that the rcpath reporting pointsWebcurie temperature.
