Significant tunneling magnetoresistance and excellent spin filtering effect in CrI3-based van der Waals magnetic tunnel junctions

The transport properties of CrI₃/h-BN/n·CrI₃ (n = 1, 2, 3, 4) MTJs under positive bias voltages exhibit an interesting odd-even effect. Significant tunneling magnetoresistance, a perfect spin filtering effect and remarkable negative differential resistance were obtained.
