Abstract

The polycrystalline Fe2Te0.95Ta0.05O6 possessing tetragonal trirutile structure with P4(2)/mnm space group is synthesized via solid state reaction route. Phase confirmation and structural parameter calculation are done by the Rietveld refinement of XRD data. We demonstrate the temperature and magnetic field dependent magnetic property and room temperature magnetoelectric (ME) behavior of the material. The temperature dependent magnetic susceptibility confirms the antiferromagnetic transition at 210K along with a broad transition prior to it due to presence of short range magnetic ordering. The typical temperature response of magnetic susceptibility like Fe2TeO6 parent material differ at 18K as it shows a transitional anomaly due to Ta doping. MH hysteresis measured at 300K and 2K shows an apparent linear behavior. A hysteretic ferromagnetic induction in low field region at 300K is observed due to doping induced modification in exchange interaction mechanisms. Presence of linear ME effect is confirmed through ME voltage measurement wit ME coefficients a/d approximate to 0.23 mV cm(-1) Oe(-1), beta/d approximate to -3.47 x 10(-4) mV cm(-1) Oe(-2), obtained by linear fit to M. Ferroelectric hysteresis loop is obtained by PE loop measurement using remanent polarization measurement with value approximate to 2.5 nC/cm(2).
