摘要

Amorphous EuTiO_3 thin films have been prepared by a pulsed laser deposition method, and their structural and magnetic properties have been investigated. High-resolution transmission electron microscope image and selected-area electron diffraction pattern as well as X-ray diffraction pattern confirm the amorphous nature of the thin films. ~(151)Eu conversion-electron M?ssbauer effect measurements show that almost all of the europium ions are present as Eu~(2+) in the thin films. The amorphous EuTiO_3 thin film exhibits a positive Weiss temperature of 8.7 K, indicating predominant ferromagnetic interactions among Eu~(2+) ions. The signature of a ferromagnetic-like transition is observed at around 5.5 K.
