Spin-orbit proximity to van der Waals's two-dimensional magnetostratigraphic structure: transition from the current antiferromagnet-pheromagnet to a reversible nonchemical phase in Bilayer CrI3.


Abstract image

The recently discovered two-dimensional magnetic insulator CrI3 It is intriguing for basic research and spintronics applications, as it is a ferromagnet in bulk, but the antifragment is bi-directional, subject to external manipulation by its magnetic order. By using the quantum transport approach of the first principles, we mean that the introduction of a nonpolarized charge is carried out in parallel with the Boeller-CRI interface.3/ monolayer-TaSe2 The van der Waals (vdW) heterostructure will spin-orbit rotation, thereby driving the magnetization dynamics of the first CRI monolayer.3 In direct contact with TaSe2. Combining the computed complicated angular dependence of spin-orbit rotation for the classical magnetization dynamics of the Landau-Lifshitz-Gilbert equation, we show that current pulses can change the magnetization direction on the first monocover to become parallel to the second monolayer. , Thereby transforming the CRI3 From antiferromagnet to ferromagnet While not requiring any magnetic fields. We explain this reversal mechanism Current-driven unskilled phase transition With the testimony of the first CRI monologues3 Conducts current through metallic transfer metal dichalcogenide TaSe due to injective wave functions2, While simultaneously acquiring a strong spin-orbit coupling through such proximity effects, and a second CRI monolayer3 Remains insulating. The transition can be ascertained through the vertical reading level, through the vdW heterostructure, which is disrupted by a hexagonal boron nitride bilayer and between the graphite electrodes in the sandwich where we find a tunneling magnetosis of 40240%.
