Abstract

We have measured the temperature-dependent X-ray diffraction pattern of a single-crystalline EuO (100) thin film to investigate the change of the lattice constant due to the ferromagnetic phase transition. No structural transition was observed and the contracting rate of the lattice constant was dramatically increases below the ferromagnetic phase transition temperature. It indicates that the hybridization intensity between the Eu 4f state and the other O 2p and Eu 5d states increases in the ferromagnetic phase.
