Abstract
Perovskite-like rhombohedral distorted solid solutions of BiFe1-х(M1/2Ti1/2)хO3 (M = Co, Ni, Zn, x = 0–0.11) were obtained by solid-phase synthesis. An indicator of the solid solution formation is the change of unit cells parameters, that corresponds to the ionic radii of mixed cations (M1/2Ti1/2)3+ (M = Co, Ni, Zn. Solid solutions of BiFe1-х(M1/2Ti1/2)хO3 (M = Co, Ni), in contrast to BiFe1-x(Zn1/2Ti1/2)xO3 demonstrate ferromagnetic hysteresis pels at room temperature. The x growth in the range from 0.01 to 0.11 for the BiFe1-х(M1/2Ti1/2)хO3 system leads to, the saturation magnetization MS and the remanent magnetization MR increase from ∼0.1 and ∼2.4⋅10−3 emu/g to ∼0.4 and ∼0.038 emu/g respectively. In the same time the coercive force Hc decreases from ∼120 to ∼80 Oe. For the BiFe1-х(Co1/2Ti1/2)хO3 system, a noticeably higher magnetic properties with a more complex dependence on x are observed. The maximum parameter values are observed at x = 0.04–0.05: MS = 0.83 and MR = 0.24 emu/g, Hc = 1.8 kOe. It is suggested that the detected anomalies of Co-containing solid solutions behavior are related to the one-ionic magnetocrystalline anisotropy of Co2+ cations. The BiFe1-х(M1/2Ti1/2)хO3 (M = Co, Ni) samples demonstrate piezoelectric constant d33 up to 7 pC/N. Due to the set of properties the materials obtained can be classified as high-temperature multiferroics.
