説明

The alkaline-earth iron perovskites AFeO3 are interesting materials since their ferromagnetic domains could be controlled by an applied magnetic field. However, to be exploited for applications, there are still some flaws related to their antiferromagnetic or ferromagnetic behavior at low temperatures. In our work, we have attempted to synthesize pristine BaFeO3 with Ba to partially or fully substitute Sr or Ca in order to tailor the magnetic properties of the host compound as expected for applications. We found that powders of (Ca/Sr/Ba) FeO3 showed an increased enhancement of magnetic properties in comparison to BaFeO3 films. In particular, the (Ca/Sr)0.5Ba0.5FeO3 nanopowders have demonstrated a Curie temperature well above room temperature along with an increased magnetic moment. A considerable coercivity is also surprisingly obtained as a typical signature for a hard magnetic material. First-principles calculations were performed to get an insight into the Ca/Sr influence on the lattice structure, and...
