| Popis: | (Tb0.874Mn0.106)Mn1−xNixO3−δ (0.0 ≤ x ≤ 0.20) solid solutions have been synthesized by solid state method. They all crystallize in orthorhombic Pnma space group with perovskite structure at room temperature. The unit cell volume decreases with an increase of Ni in (Tb0.874Mn0.106)Mn0.80Ni0.20O3−δ. The samples show two magnetic orderings. The temperature dependent dielectric constant shows an abnormal step like increase for all the solid solutions. The dielectric constants decrease with an increase in frequency. The activation energies calculated from dielectric loss are related to the oxygen vacancies in the samples. |
