Enhanced magnetoresistance in mixed van der Waals magnetic tunnel junctions
ORAL
Abstract
Since the recent isolation of monolayer CrI3, there has been a surge of interest in van der Waals heterostructures incorporating 2D magnets. Studies have demonstrated large tunneling magnetoresistances in van der Waals magnetic tunnel junctions fabricated from the insulating layered chromium trihalides (CrX3) due to the spin filter effect. Here, we report electron tunneling in graphite/CrCl3/CrBr3/graphite van der Waals heterostructures to study the effect of the CrCl3/CrBr3 interface. We find that the magnetoresistance persists above the Néel temperature of the in-plane antiferromagnet CrCl3 with enhanced values compared to magnetic tunnel junctions fabricated from CrCl3 alone. We interpret these data as resulting from the out-of-plane ferromagnet CrBr3 acting as a spin-polarizing layer.
