Easy synthesis and electric, magneto-transport and magnetic properties of double perovskite La sub(2)CoMnO sub(6) compound

We report synthesis of double perovskite La sub(2)CoMnO sub(6) compound by a simple solid state reaction method. The samples sintered at different temperatures showed single phase nature with monoclinic P2 sub(1)/n space group. The phase purity was confirmed through the presence of characteristic Ra...

Description
Summary:We report synthesis of double perovskite La sub(2)CoMnO sub(6) compound by a simple solid state reaction method. The samples sintered at different temperatures showed single phase nature with monoclinic P2 sub(1)/n space group. The phase purity was confirmed through the presence of characteristic Raman scattering modes. The samples exhibited semiconducting behavior without any anomaly in the temperature range 125 K less than or equal to T less than or equal to 300 K. The maximum magnetoresistance value at low temperature was around 40 %. The electric and magneto-transport behaviors were governed by variable range hopping mechanism. A single paramagnetic to ferromagnetic transition and well saturated hysteresis loops, indicative of ordered phase were observed in these samples.
