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

The transferred average strain εave and corresponding magnetic domain evolution processes in the d ~ 350 nm a [Pt/Co/Ta]12 and b [Pt/Co/Ta]8 nano-dots in a cycle of E ranging from +10 to −10 kV cm−1. Positive εave (red dots) represents tensile strain while negative εave (blue dots) represents compressive strain. μ0H represents the external magnetic field except that from the MFM tip and here μ0H is equal to be 0 mT. The inset of b illustrates the spin texture of the magnetic domain that is encompassed by the red box. The stripe domain enclosed by the black box shows the initial state of the magnetic domain evolution path. The gray dots represent the corresponding electric field for the MFM images. The MFM contrast represents the MFM tip resonant frequency shift (Δf). The scale bar represents 250 nm.
