Room-temperature ferromagnetic materials with perpendicular magnetic anisotropy are widely sought after for spintronics, magnetic data storage devices, and stochastic computing. To address this need, a new Fe-BaTiO3 vertically aligned nanocomposite (VAN) has been fabricated—combining both the strong room-temperature ferromagnetic properties of Fe nanopillars and the strong room-temperature ferroelectric properties of the BaTiO3 matrix. Furthermore, the Fe-BaTiO3 VAN allows for highly anisotropic magnetic properties with tunable magnetization and coercivity. In addition, to demonstrate the multiferroic properties of the Fe-BaTiO3 system, the new metal-oxide hybrid material system has been incorporated in a multilayer stack. This new multiferroic VAN system possesses great potential in magnetic anisotropy and property tuning and demonstrates a new material family of oxide-metal hybrid systems for room-temperature multiferroic material designs.
