Despite being applied with success in many fields of materials science, Raman spectroscopy is not yet determinant in the study of electroceramics. Recent experimental and theoretical developments, however, should increase the popularity of Raman spectroscopy in this class of materials. In this review, we outline the fields of application of Raman spectroscopy and microscopy in various electroceramic systems, defining current key bottlenecks and explaining promising recent developments. We focus our attention on recent experimental developments, including coupling Raman spectroscopy with other methodologies and modelling approaches involving both the model-based data interpretation and the ab initio calculation of realistic Raman spectra.

Composite materials consisting of two dissimilar ferroic phases are an excellent alternative to single-phase multiferroics for a wide range of magnetoelectric technologies. In composites with strain-mediated magnetoelectric coupling the response is strongly dependent on the characteristics of the interface between the two mechanically coupled phases. Among the different material approaches considered, cofired ceramic composites offer improved reliability in applications and are more adequate for free-forming and miniaturization. However, their magnetoelectric response often suffers from poor reproducibility, which has been reiteratively associated with the quality of the interfaces with little experimental support. Here, we report an in-depth study of the local material properties across the interfaces of 0.36BiScO-0.64PbTiO/NiFeO multilayer ceramic composites, processed by spark plasma sintering of nanocrystalline powders. Tailored microstructures and low residual stress levels were obtained by adjusting the sintering mismatch between the two ferroic phases, which also resulted in fully functional interfaces and enhanced magnetoelectric responses.

“…Since displacive transitions as those found in ferroelectrics have an optical mode that softens to zero near the transition, Raman spectroscopy has been extensively used to study ferroelectric phase diagrams. [160][161][162][163][164] Despite the challenges in analysis posed by peak broadening and mixing (quasi modes), Raman spectroscopy is an established technique to study complex disordered solids. A novel work from Yang et al 165 realized nanoscale spatial resolution to reveal local structural heterogeneity and visualize short-range atomic ordering in amorphous Si using tip-enhanced Raman spectroscopy.…”
