Two-Dimensional Triferroics: From Fundamental Couplings to Multifunctional Applications

Area of Science:

• Materials Science
• Condensed Matter Physics

Background:

• Triferroic compounds exhibit coexistence and coupling of more than two ferroic orders, presenting a novel class of multiferroic materials.
• The involvement of a third ferroic order allows for complex, tunable functional responses and deterministic multistate control, surpassing conventional pairwise coupling in multiferroics.

Purpose of the Study:

• To provide a comprehensive overview of recent advancements in two-dimensional (2D) triferroic materials.
• To focus on the origin and interplay of multiple ferroic orders at structural and electronic levels within these 2D systems.

Main Methods:

• Review of existing literature on 2D triferroic materials.
• Analysis of structural and electronic mechanisms governing ferroic order interplay.

Main Results:

• Triferroicity, previously limited to 3D systems, is now being explored in 2D materials, offering advantages like high storage density and flexibility.
• Understanding the interplay of ferroic orders is key to unlocking novel functionalities.

Conclusions:

• 2D triferroic materials hold significant promise for applications in multistate data storage and spintronic devices.
• Future research should focus on exploring new 2D triferroic systems and optimizing their properties for technological applications.
