Ferroelectricity, Multiferroicity, and Magnetism in Low-Dimensional Nanomaterials

Dear Colleagues,

The study of ferroelectricity began with bulk materials like BaTiO₃ in the 1940s, followed by multiferroics (e.g., BiFeO₃) combining ferroelectricity and magnetism. However, bulk systems suffer from weak magnetoelectric coupling. The rise of 2D materials, starting with graphene, transformed the field by enabling quantum-confined states and interfacial control. Landmark discoveries—such as 2D ferroelectricity in SnTe (2016) and multiferroicity in NiI₂—reshaped the understanding of polarization and magnetism at atomic scales, paving the way for novel nanoelectronics and spintronics.

This Special Issue aims to provide a comprehensive overview of the latest advancements in ferroelectricity, multiferroicity, and magnetism in low-dimensional nanomaterials. It seeks to highlight fundamental principles, innovative experimental techniques, and theoretical models that advance our understanding of these phenomena. Recent research has made significant strides in this area. For example, the coexistence of altermagnetism and ferroelectricity in 2D materials like Cr₂SeO has been explored, demonstrating the potential for designing materials with tailored magnetic and electric properties. Studies on the piezoelectric properties of Janus Cr₂SeO monolayers have shown robust ferroelectricity at room temperature. Additionally, the discovery of intrinsic ferroelectricity in materials such as SnTe and CuInP₂S₆ has opened new avenues for the development of next-generation nanoscale devices. These advancements highlight the potential of low-dimensional nanomaterials to revolutionize modern electronics and spintronics.

We invite researchers to submit original research articles, review papers, and ideas on relevant topics.
