Weak ferromagnetism in CeMn2-xSi2+x crystals with a mixed cerium valence
Levin E. M., Pustovit A. V., Markovskii A. A.
The appearance of a weak ferromagnetism in the antiferromagnetic manganese sublattice and a simultaneous change in the properties of the electronic structure of the crystal near the Fermi level due to 4f states of valence-unstable cerium have been observed in CeMn2 _ xSi2 + x alloys of variable composition upon the substitutions Mn «=t Si.
