“…A reduction in hysteresis under high stress has been observed in lanthanum doped PZT (PLZT) [51] and PZT [10,52,53]. The hysteresis loop changes shape from a square loop to a slanted loop under compressive stress with a corresponding decrease in remanent polarisation P r and coercive field E c , as has been observed previously [10,[51][52][53][54]. Between 5 MPa and 50 MPa P r and E c decrease by approximately 33% and 10%, respectively.…”

Measurement and calculation of anhysteretic curves is a well-established method in the field of magnetic materials and is applied to ferroelectric materials here. The anhysteretic curve is linked to a stable equilibrium state in the domain structure, and ignores dissipative effects related to mechanisms such as domain wall pinning. In this study, an experimental method for characterising the anhysteretic behaviour of ferroelectrics is presented, which is subsequently used to determine the anhysteretic polarisation response of polycrystalline barium titanate and a doped lead zirconate titanate composition at room temperature. Various external parameters, such as electric field, stress, and temperature, can significantly affect ferroelectric behaviour. Ferroelectric hysteresis curves can assess the importance of such effects but cannot distinguish their contribution on the different intrinsic and extrinsic mechanisms involved in ferroelectric behaviour. In this work, the influence of compressive stress on the anhysteretic polarisation is measured and discussed. The comparison of the polarization loop to the anhysteretic curve under compressive stress elucidates the effects on the stable equilibrium domain configuration and dynamic effects associated to dissipation.

“…However, dielectric loss increases continuously with increasing stress. Similar experimental phenomena have been obtained in Fe 3+ /Nb 5+ doped BaTiO 3 ceramics [18], and Pb(Mg 1/3 Nb 2/3 )O 3 -PbTiO 3 ceramics [19], where dielectric constant decreases, and dielectric loss increases with increasing the external stresses. Interestingly, the stress-induced shift of cubic-tetragonal (C-T) phase transition of Ba 0.65 Sr 0.35 TiO 3 ceramics was observed.…”

“…This was con-firmed by the investigation on the electromechanical properties of 8/65/35 PLZT ceramics under uniaxial compressive stress, where both P s and P r were found to decrease with respect to increasing stress. 72 Later, this observation was also verified in soft PZT, 223 Fe 3+ /Nb 5+ BaTiO 3 , 224 Pb(In 0.5 Nb 0.5 ) O 3 -PT, 225 and PZT-885. 226 A typical evolution of the hysteresis loops with respect to the uniaxial stress is given in Fig.…”

Decoding the Fingerprint of Ferroelectric Loops: Comprehension of the Material Properties and Structures

Due to the nature of domains, ferroics, including ferromagnetic, ferroelectric, and ferroelastic materials, exhibit hysteresis phenomena with respect to external driving fields (magnetic field, electric field, or stress). In principle, every ferroic material has its own hysteresis loop, like a fingerprint, which contains information related to its properties and structures. For ferroelectrics, many characteristic parameters, such as coercive field, spontaneous, and remnant polarizations can be directly extracted from the hysteresis loops. Furthermore, many impact factors, including the effect of materials (grain size and grain boundary, phase and phase boundary, doping, anisotropy, thickness), aging (with and without poling), and measurement conditions (applied field amplitude, fatigue, frequency, temperature, stress), can affect the hysteretic behaviors of the ferroelectrics. In this feature article, we will first give the background of the ferroic materials and multiferroics, with an emphasis on ferroelectrics. Then it is followed by an introduction of the characterizing techniques for the loops, including the polarization–electric field loops and strain–electric field curves. A caution is made to avoid misinterpretation of the loops due to the existence of conductivity. Based on their morphologic features, the hysteresis loops are categorized to four groups and the corresponding material usages are introduced. The impact factors on the hysteresis loops are discussed based on recent developments in ferroelectric and related materials. It is suggested that decoding the fingerprint of loops in ferroelectrics is feasible and the comprehension of the material properties and structures through the hysteresis loops is established.
