Zusammenfassung: | Achieving giant magneto-optical birefringence is a long-standing goal in view of its
intriguing physics and potential applications in transmitted light modulation. Due to the
unique geometric features of two-dimensional materials with extremely large shape
anisotropy, the resultant couplings among magnetic, electric, and optical properties
enable giant magneto-optical birefringence effects, as represented by a record-breaking
magneto-optical Cotton–Mouton coefficient in two-dimensional material systems. In this
Perspective, we introduce the discovery of the giant magneto-optical birefringence effect
in two-dimensional metal oxide dispersion in 2020, followed by analyses of the underlying
mechanisms. We then discuss how the interplay of anisotropy and colloidal behavior affects
the Cotton–Mouton effect. Finally, we proceed to potential applications and give our ideas
about future developments in this emerging field. |
