Abstract: The electrical resistivity of Eu-rich EuO thin films was studied at temperatures 5≤T≤150 K and magnetic fields 0≤H≤5 T. We prepared two films with different degrees of off-stoichiometry using the method described previously. [Jpn. J. Appl. Phys. 35 (1996) 6052] The film richer in Eu exhibited an increase in Curie temperature of the bulk value of 70 K to approximately 150 K, and zero-field resistivity decreased from about 100 µ Ω·m at 100 K to 5 µ Ω·m at 20 K. The film's magnetoresistance exceeded -80% in the 80–90 K temperature range. These results show that the stable reproduction of EuO films with high levels of conductivity without the addition of a third element is now possible.
