Claim:
1. A permanent magnet material containing the compound, Ce(Fe 12−x Si x ), having the tetragonal ThMn 12 crystal structure, space group I4/mmm, #139 and where x has a value in the range of one to four, the compound Ce(Fe 12−x Si x ), having been prepared from a melt consisting of cerium, iron, and silicon and the melt having been rapidly solidified at a cooling rate to form particles of a permanent magnet material containing the compound having the tetragonal ThMn 12 crystal structure, space group I4/mmm, #139, the particles of permanent magnet material having a magnetic moment value, 4πMs, in the range of 1.04 to 1.27 Tesla, the Ce(Fe 12−x Si x ) compound contains one or more of Ti, V, Cr, and Mo in combination with Si such that the combination provides a value of x in the range of 1-4 and Si comprises at least 0.1 x.
