The observation of ferromagnetism in CeCo3B2 with a high Curie
temperature TC = 140 K and a magnetic moment 8×10- 3\muB
/F.U has been presented and explained by 4f itinerant magnetism with strong
4f-4f direct exchange interaction. The observed small magnetic moment
can be understood
by a cancellation of 4f orbital and spin contributions and of 5d
polarized contribution to magnetic moment.
