 In contrast with the other rare @-@ earth metals , which usually have antiferromagnetic and / or ferromagnetic properties at low temperatures , ytterbium is paramagnetic at temperatures above 1 @.@ 0 kelvin . However , the alpha allotrope is diamagnetic . With a melting point of 824 ° C and a boiling point of 1196 ° C , ytterbium has the smallest liquid range of all the metals .
