In the present work we report the magnetoelectric characterization of the new manganite Sr2TiMnO6 perovskite-like material. From measurements of magnetization as a function of temperature we determine the occurrence of a magnetic ordering for a critical temperature Tc=44.8 K and the existence of an irreversibility point at the magnetization measurements as a function of temperature for the Zero Field Cooling (ZFC) and Field Cooling (FC) regimes, became a strong evidence of frustration. Curves of magnetization as a function of applied field show a hysteretic behavior, characteristic of ferromagnetic materials. Curves of polarization as a function of applied voltage exhibit a ferroelectric response. Results reveal the occurrence of magnetoelectric response for the temperature regime T<44.8 K.
