Dysprosium is a chemical element; it has symbol Dy and atomic number 66. It is a rare-earth element in the lanthanide series with a metallic silver luster. Dysprosium is never found in nature as a free element, though, like other lanthanides, it is found in various minerals, such as xenotime.
Above the Curie temperature, the magnetic spins are randomly aligned in a paramagnet unless a magnetic field is applied. In physics and materials science, the Curie temperature (TC), or Curie point, is the temperature above which certain materials lose their permanent magnetic properties, which can (in most cases) be replaced by induced magnetism.

Praseodymium. double hexagonal close-packed (dhcp) (hP4) Praseodymium is a chemical element; it has symbol Pr and the atomic number 59. It is the third member of the lanthanide series and is considered one of the rare-earth metals. It is a soft, silvery, malleable and ductile metal, valued for its magnetic, electrical, chemical, and optical ...
Dysprosium oxide (Dy 2 O 3) is a sesquioxide compound of the rare earth metal dysprosium. It is a pastel yellowish-greenish, slightly hygroscopic powder having specialized uses in ceramics, glass, phosphors, lasers, dysprosium metal halide lamps, and as a Faraday rotator. [3] It can react with acids to produce the corresponding dysprosium(III ...
Properties. Dysprosium (III) phosphate decomposes into dysprosium oxyphosphate and phosphorus pentoxide above 1200 °C. [2] It reacts with sodium fluoride to obtain NaDyFPO 4: [3] NaF + DyPO4 → NaDyFPO4. It reacts with sodium molybdate at high temperature to generate Na 2 Dy (MoO 4) (PO 4): [4] Na2MoO4 + DyPO4 → Na2Dy (MoO4) (PO4)
