Wikipedia (Praseodymium is a soft, silvery, malleable and ductile metal in the lanthanide group. It is valued for its magnetic, electrical, chemical, and optical properties. It is too reactive to be found in native form, and when artificially prepared, it slowly develops a green oxide coating.)
It is paramagnetic at room temperature. Susceptibility = +5.530E-3 emu/mol from
Antiferomagnetic with Neel temperature approximately 740 K.
