Magnetic properties of Sr<sub>2</sub>FeTaO<sub>6</sub> double perovskite epitaxially grown by pulsed-laser deposition
Abstract
We have investigated the magnetic properties of B-site-ordered Sr<sub>2</sub>FeTaO<sub>6</sub> double perovskite thin films grown on (111) SrTiO<sub>3</sub> substrates by using pulsed-laser deposition. High degree of ordering of Fe and Ta ions has been confirmed using x-ray diffraction and atomically resolved high-angle annular dark-field scanning transmission electron microscopy. We have found clear signatures of magnetic frustration in {111} planes of local spin moment arising from next-nearest-neighbor interaction in triangular FeO<sub>6</sub> sublattice below 50 K. It is also found that this behavior is suppressed by increasing disorder and eventually leads to antiferromagnetic state.
