Growth of 2D Cr2O3–CrN Mosaic Heterostructures with Tunable Room‐Temperature Ferromagnetism (Adv. Mater. 7/2024)

Ferromagnetism The two-dimensional Cr2O3-CrN mosaic heterostructures consisting of a Cr2O3 flake with embedded CrN subdomains are synthesized by a designed chemical vapor deposition method. These mosaic heterostructures exhibit room-temperature ferromagnetism which correlates with the Cr2O3-CrN interfaces as shown in the cover image. More details can be found in article number 2304946 by Jingwei Wang, Bilu Liu, and co-workers.
