Magnetoelectric response of new Sr 2TiMnO 6 manganite-like material

We report synthesis and characterization of new Sr ₂TiMnO ₆ manganite-like material. Samples were produced by the solid state reaction method. X-ray diffraction experiments reveal the presence of peaks, which are characteristics of the complex perovskite systems. Rietveld refinement showed that Sr ₂TiMnO ₆ crystallizes in a tetragonal structure, which corresponds to the space group I/4m. From measurements of magnetization as a function of temperature, we determine the occurrence of magnetic ordering for a critical temperature T_C=44.8 K and strong evidence of frustration. Curves of magnetization as a function of applied field show hysteretic behavior. Curves of polarization as a function of applied voltage exhibit the ferroelectric response of Sr ₂TiMnO ₆ material. Results reveal the occurrence of magnetoelectric response for the temperature regime T<44.8 K.
