Abstract

Nanocrystalline films of La-doped CaB6 have been fabricated by using a rf-magnetron sputtering. Lattice expansion of up to 6% with respect to the bulk value was observed along the direction perpendicular to the film plane, which arises from the trapping of Ar gas into the film. Large ferromagnetic moment of 3-4 μB/La has been observed in some La-doped films only when the lattice expansion rate is larger than 2.5%.
