Unlike most lanthanides at ambient pressure, Yb does not order magnetically and Pr orders at temperatures well below 1 K, since divalent Yb is magnetically inert with a completely filled 4f14 orbital and trivalent Pr has a crystal-field-split singlet ground state. Applying extreme pressure can significantly alter both the electronic and crystal structure of materials and thus possibly induce magnetic ordering in Yb or Pr at temperatures above 1 K.
