The thin films were deposited on yttria-stabilized ZrO (111) substrates using reactive magnetron sputtering. The magnetization measurement showed that the saturation magnetization is 7 /Eu atom, indicating that the EuH films are nearly stoichiometric (x 2.0) and that the Curie temperature is 20 K. The optical measurements showed a bandgap of 1.81 eV. These values are similar to those previously reported for bulk EuH. This study paves the way for the application of metal hydrides in the field of electronics through the fabrication of high-quality metal hydride epitaxial thin films.
