Correlations in Magnetic Sub-Domains as an Unconventional Phase Diagram for van der Waals Ferromagnets

Figure 1 Coexistence of several domain sub-systems. a,d) MFM images obtained from CrBr3 crystals with thicknesses of 190 nm (a) and 300 nm (d), demonstrating complex patterns consisting of multiple systems of domains. Image (a) was deconvoluted into figures (b) and (c), and (d) into (e) and (f) using FFT filtering to highlight several overlaying domain patterns. The similarity index for domain sub-groups (b) and (c) is ξ = 0.26, and for (e) and (f) is ξ = 0.13. The sample-tip distance was 50 nm for (a) and 100 nm for (d).

Two-dimensional van der Waals ferromagnets continue to reveal unexpected magnetic phenomena that challenge the traditional understanding of magnetic ordering. In this article, Sergey Y. Grebenchuk,… Read More »Correlations in Magnetic Sub-Domains as an Unconventional Phase Diagram for van der Waals Ferromagnets
