We report on the preparation, structure, and magnetic properties of amorphous EuZrO3, an amorphous ferromagnetic oxide. The samples were prepared in the form of thin film through a pulsed-laser-deposition method and their structure was confirmed to be amorphous by X-ray diffraction and high-resolution transmission electron microscope observation. Amorphous EuZrO3 thin films exhibit a ferromagnetic transition and reenter into a spin glass phase at a lower temperature, while crystalline EuZrO3 is an antiferromagnet as reported previously. The difference in magnetic properties between amorphous and crystalline EuZrO3 is suggested to arise from the difference in their structures.
