High density magnetic field
Web10 de abr. de 2024 · 1.Introduction. All large scale applications of high-temperature superconductors depend crucially on two particular parameters; the temperature and field dependent critical current density, J c (T,H) [1], [2], [3] and temperature dependent irreversibility magnetic field, H irr (T) [4], [5], [6].The superconducting (SC) critical … 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
