Table 2 The numbers of electrons in the majority-spin \(({n}_{\uparrow })\) and minority-spin \(({n}_{\downarrow })\) states and spin magnetic moments (ยต s ) of the interface (I) atoms for FeRh/MgO in the most stable AFM(IV)/FM(IO) phase and Ta/FeRh/MgO in the most stable FM(ITa)/FM(IO) phase. The letters IO and ITa denote the interfaces next to the MgO and Ta layers, respectively. The letter IV denotes the interface of FeRh/MgO next to the vacuum level, where the local spin states and magnetic moments of the Fe(IV) atom are shown.
