Table 2.

The numbers of electrons in the majority-spin $(n_{\uparrow })$ and minority-spin $(n_{\downarrow })$ states and spin magnetic moments (µ_s) of the interface (I) atoms for FeRh/MgO in the most stable AFM(I_V)/FM(I_O) phase and Ta/FeRh/MgO in the most stable FM(I_Ta)/FM(I_O) phase. The letters I_O and I_Ta denote the interfaces next to the MgO and Ta layers, respectively. The letter I_V denotes the interface of FeRh/MgO next to the vacuum level, where the local spin states and magnetic moments of the Fe(I_V) atom are shown.
