Article Synopsis
- Epitaxial graphene/ferromagnetic metal heterostructures are promising for spintronic devices due to their unique magnetic properties and stability.
- The research focuses on understanding the spin-orbit coupling at the interface of graphene and cobalt on iridium, revealing that hybridization contributes to strong coupling effects.
- Findings indicate that while thin cobalt layers exhibit significant spin-orbit effects, these vanish with thicker layers, highlighting the importance of graphene's electronic interactions for future spintronic applications.
While technologically challenging, the integration of ferroelectric thin films with graphene spintronics potentially allows the realization of highly efficient, electrically tunable, nonvolatile memories through control of the interfacial spin-orbit driven interaction occurring at graphene/Co interfaces deposited on heavy metal supports. Here, the integration of ferroelectric HfZrO on graphene/Co/heavy metal epitaxial stacks is investigated via the implementation of several nucleation methods in atomic layer deposition. By employing in situ AlO as a nucleation layer sandwiched between HfZrO and graphene, the HfZrO demonstrates a remanent polarization (2Pr) of 19.
