Weak ferromagnetism, inflated dielectricity with improved resistive property in the morphotropic phase composition of (1 − x) Bi_1−yHo_yFeO₃–xBa_0.8Ca_0.2TiO₃ (0.25 ≤ x ≤ 0.4; y = 0.025) ceramic solid solutions

In this investigation, a series of (1 − x) Bi_1−yHo_yFeO₃–xBa_0.8Ca_0.2TiO₃ (0.25 ≤ x ≤ 0.4; y = 0.025) ceramic solid solutions were synthesized using a conventional solid-state reaction route. The primary goal of this study was to perceive the significance of substitution on the structural, magnetic, dielectric, and resistive properties of the ceramic solid solution. The investigation suggested the trace of weak ferromagnetism in all of the samples. A methodical XRD-based phase structural study revealed a presence of a morphotropic phase boundary (MPB) in the range of 0.3 ≤ x ≤ 0.35, showing robust dielectric properties in the MPB region, as verified by the dielectric measurements. A room temperature A.C conductivity study and activation energy calculation advocated an improved resistive property in the x = 0.3 sample.
