Fig. 1: Schematic of an all-antiferromagnetic tunnel junction down to the atomic limit.
From: Twist-assisted all-antiferromagnetic tunnel junction in the atomic limit
a, Schematic structure of a conventional MTJ. b, A conventional MTJ with FM electrodes. c, A conventional MTJ based on non-collinear AF electrodes. d, Schematic structure of a 2D MTJ with nonmagnetic metallic electrodes and an insulating 2D magnetic tunnel barrier. e, Schematic diagram of the two magnetic states (‘1’ and ‘0’) of an untwisted 2D MTJ. The MTJ is formed from two AF bilayers. Upper drawing shows side views of the respective spin configurations. Lower drawing shows top views of the respective spin configurations at the mid-interface. f, Schematic diagram of the two magnetic states (1, ‘ZF-off’ and 0, ‘ZF-on’) of a twisted 2D MTJ. Upper drawing shows side views of the respective spin configurations. Lower drawing shows top views of the respective spin configurations at the twisted interface.
