ABSTRACT:
The invention relates to new hard magnetic materials which have an intermetallic compound of tetragonal crystal structure of the ThMn.sub.12 type. The intermetallic compound has the gross formula ZA(Me.sup.I.sub.1-x Me.sup.II.sub.x).sub.12, wherein ZA is a rare earth metal from the group Sm, Er, Tm. Me.sup.I is Fe, Co or a mixture of the two, Me.sup.II is Ti, V, Cr or Si and x=0.1-0.2, preferably 0.12-0.17.
