Fig. 4: ETMR effect in Mn3GaN/SrTiO3/Mn3GaN (001) AFMTJ.
From: Nearly perfect spin polarization of noncollinear antiferromagnets
a Atomic structure of perovskite oxide SrTiO3. b The lowest decay rate \({\kappa }_{{{\boldsymbol{k}}}_{{\|}}}\) of the evanescent states of SrTiO3 (001) in the 2DBZ calculated at the energy close to the bottom of the conduction band. c Atomic structure of the AFMTJ. The Néel vectors of the Mn3GaN electrodes lie in the [111] plane (not shown) and can be parallel or antiparallel. d Layer-resolved density of states (LDOS) for parallel Néel vectors. Calculated \({{\boldsymbol{k}}}_{{\|}}\)-resolved transmission in the 2DBZ for the AFMTJ for parallel (P) (e) and antiparallel (AP) (f) alignment of the Néel vector in Mn3GaN electrodes. g Total transmission and ETMR ratio as functions of energy.
