Structural, dielectric and impedance analysis of Nd-doped BiFeO3 prepared using solid-state synthesis method

Influence of A‐Site Doping on the Local Structure and Magnetic Behavior of BiFeO3 Nanoparticles Investigated by X‐Ray Absorption Fine Structure Spectroscopy

“…Obviously, the introduction of rare‐earth ions with a smaller ionic radius than Bi 3+ inhibits crystal formation to some extent, resulting in a reduction in average grain size. [ 27,50 ]…”

“…Obviously, the introduction of rare-earth ions with a smaller ionic radius than Bi 3þ inhibits crystal formation to some extent, resulting in a reduction in average grain size. [27,50] The magnetization hysteresis loops of all samples for the maximum magnetic field of 60 kOe at room temperature are depicted in Figure 3. It is obvious that the host BFO displays a nearly straight line indicating its antiferromagnetic nature; in addition, the weak magnetization, which cannot be observed due to a cancellation of magnetization on macroscopic scale subjected by cycloidal modulation of 62 nm, [10,51] is captured in the pure BFO, implying the existence of nanoparticles that already have been observed from SEM pattern.…”
