Multiferroic behavior in glass-crystal nanocomposites containing Te2NiMnO6

► A new double perovskite crystal Te2NiMnO6 in nanocrystalline form has been synthesized in a TeO2-based glass. ► The nanocomposites prepared show ferromagnetic behavior in the temperature range 2-300 K. ► The nanocomposites also exhibit ferroelectric characteristics. ► The specimens show magnetodielectric effect.
