Thin FeRh film was extensively studied recently, and an emergent substrate-and capping-dependent interfacial ferromagnetism (FM) was widely observed inexperiments. However, the voltage modulation of this interfacial ferromagnetismis barely studied, which would have profound applications in antiferromagnetic(AFM) FeRh-based magnetoelectric-random access memory (MeRAM). Using ab initiotechniques, we comparatively study the interfacial ferromagnetic properties andmagnetoelectric responses of ultrathin FeRh films capped by heavy transitionmetal Ta. We find that Ta capping reverses the phase stability of ultrathinFeRh film below 1.5 nm and gigantically stabilizes the ferromagnetic phase andinterfacial ferromagnetism. Besides, small magnetic moment of 2.2 $\mu_B$ forneighboring Fe atoms, regardless of magnetic configurations and film thickness,is induced by Ta capping. Compared with FeRh/MgO bilayers, magneticanisotropies (in-plane for AFM, perpendicular for FM and interfacial-FMreconstructed trilayers) and magnetoelectric responses of these trilayers areenhanced. Furthermore, the VCMA behavior in FM phase is changed from$\vee$-shaped to linear. These findings demonstrate the manipulation ofmagnetic ordering of FeRh films with heavy metal capping and electric field andcan promote the application of FeRh alloy in magnetic memory andantiferromagnetic spintronics.
