Magnetic Ordering in (1-x)BaTiO3-xLaFeO3 Solid Solutions

Solid solutions between $BaTiO_3$ and $LaFeO_3$ have been prepared through a solid state reaction method. The X-ray diffraction results reveal that $Ba_{1-x}La_xTi_{1-x}Fe_xO_3$ ($0.1\;{\leq}\;x\;{\leq}\;0.7$) compounds have a cubic structure, whereas the parent material $BaTiO_3$ has a tetragonal structure. The magnetization measurements indicate that the materials have a magnetic ordering at room temperature and the magnetic properties of the solid solutions depending on the doping amount of $LaFeO_3$. The origin of magnetic behaviors is believed to be from $Fe^{3+}$ ions.
