Solid solutions of Pb1-xTbxTi1-xMnxO3 (0≤x≤0.10) were synthesized by a traditional solid state reaction and characterized by powder X-ray diffraction. The solutions crystallize in the P4mm space group at room temperature. Differential scanning calorimetry (DSC) measurements were performed to obtain phase transition temperatures (Tc) for the samples, and these were found to decrease with an increase in the amount of doped Tb and Mn. The temperature dependent dielectric constant shows a peak close to the Tc, indicating that the corresponding phase transition is a ferroelectric phase transition. Magnetic measurements indicate that a paramagnetic to antiferromagnetic phase transition occurs at 25 and 29 K for Pb1-xTbxTi1-xMnxO3 with x=0.08 and x=0.10, respectively.
