Abstract K1-xCaxNbO3 (x = 0–0.2) ceramic samples were prepared by self-sacrifice method to study the effects of Ca2+ doping on the crystal structure, dielectric properties and magnetic phase transition of KNbO3. XRD analysis showed that all samples belong to a single-phase orthogonal crystal system with a spatial group of Amm2. The valence states of K, Nb and O elements, the atomic proportion in K1-xCaxNbO3 (x = 0–0.2) samples, and the relationship between the binding energies of K, Nb and O and...

Abstract The effects of Cr3+ doping on the crystal structure, dielectric and magnetic phase transition of SmFeO3 have been investigated. The XRD pattern analysis shows that all the peaks for SmFe1-xCrxO3 samples can be indexed according to the crystal structure of pure SmFeO3 and has a fine crystal structure. The dielectric constants of SmFe1-xCrxO3 (x = 0.1–0.3) ceramics (er = 2532, 1959, 1172) are only 0.86, 0.67 and 0.41 times that of SmFeO3 (er = 2914) at 1 kHz, respectively. The change of d...

Abstract In the present study, crystal structural, dielectric, ferromagnetic properties and high temperature magnetic phase transition of Sm1-xCaxFeO3 (x = 0–0.3) by the conventional solid-state reaction method were investigated. The crystalline structure, the microstructure, the dielectric property of the Sm1-xCaxFeO3 samples was characterized by x-ray diffraction (XRD) and field emissions canning electron microscopy (FESEM). The dielectric property measurement was performed by a precision impe...

Abstract Multiferroic Bi 1-x Ho x FeO 3 (x = 0, 0.05, 0.1) ceramics have been prepared by rapid liquid phase sintering method. The effect of Ho 3+ doping on the crystal structure, dielectric, ferroelectric properties, T N and T M of BiFeO 3 ceramics is studied. The result shows that all the peaks for Bi 1-x Ho x FeO 3 samples can be indexed according to the crystal structure of pure BiFeO 3 by XRD and the grain size from 1 to 5 μm is observed for BiFeO 3 samples with Ho 3+ doped. The dielectric ...
