Special Issue Information

Dear Colleagues,

Ferroelectric materials, including piezoelectric materials, electro-optical crystals, etc., are widely used in memory, converters, detectors, and so on. Magnetic materials use their various magnetic properties and special effects to make components or devices for storing, transmitting, and converting electromagnetic energy and information. Multiferroic materials can realize the mutual coupling of multiple physical fields such as force, electricity, and magnetism, and have important application prospects in the field of low-power magnetoelectric devices and storage. Therefore, we would like to invite you to contribute to this Special Issue of Materials, titled “Ferroelectric, magnetic, and multiferroic materials and applications”. This issue aims to collect the most recent advances in ferroic ceramics and thin films, and their new applications in energy storage, sensing, information storage, and more.

In this Special Issue, we would like to welcome all contributions from this broad field, including, but not limited to, the following topics:

  • Ferroelectric, piezoelectric, and dielectric materials;
  • Magnetism and magnetic materials;
  • Multiferroic and magnetoelectric materials;
  • Recent advances in ferroic ceramics and thin films technology and applications in energy storage and memory, etc.

Bismuth sodium titanate (Bi0.5Na0.5TiO3, BNT) ceramics are expected to replace traditional lead-based materials because of their excellent ferroelectric and piezoelectric characteristics, and they are widely used in the industrial, military, and medical fields. However, BNT ceramics have a low breakdown field strength, which leads to unsatisfactory energy storage performance. In this work, 0.85Bi0.5Na0.5TiO3-0.15LaFeO3 ceramics are prepared by the traditional high-temperature solid-phase reaction method, and their energy storage performance is greatly enhanced by improving the process of buried sintering. The results show that the buried sintering method can inhibit the formation of oxygen vacancy, reduce the volatilization of Bi2O3, and greatly improve the breakdown field strength of the ceramics so that the energy storage performance can be significantly enhanced. The breakdown field strength increases from 210 kV/cm to 310 kV/cm, and the energy storage density increases from 1.759 J/cm3 to 4.923 J/cm3. In addition, the energy storage density and energy storage efficiency of these ceramics have good frequency stability and temperature stability. In this study, the excellent energy storage performance of the ceramics prepared by the buried sintering method provides an effective idea for the design of lead-free ferroelectric ceramics with high energy storage performance and greatly expands its application field.
