Magnetoelectric antiferromagnets play an important role as a platform for spintronic applications including all electrical reading and writing of magnetic memories. In this paper we investigate the formation of domains in thin-film Cr2O3 using a combination of NV magnetometry and zero offset Hall magnetometry (ZOHM). We develop a model of the domain formation and extract important parameters, including the intergranular exchange coupling and critical temperature distribution.
