Table 1 Values of the c/a ratio and the interlayer distances (d in Å) at the interfaces for FeRh in the most stable AFM, FeRh/MgO in the AFM(IV)/FM(IO), and Ta/FeRh/MgO in the FM(ITa)/FM(IO) phase. The letters IO and ITa denote the interfaces next to the MgO and Ta layers, respectively. The same in-plane lattice (a) of 2.978 Å was employed for each system.

From: Interfacial magnetic-phase transition mediated large perpendicular magnetic anisotropy in FeRh/MgO by a heavy transition-metal capping
