报告摘要:
One of the central challenges in realizing magnetoelectric (ME) devices lies in finding a deterministic way to modulate magnetism in integrated circuits with a circuit-operation voltage.Ionic liquid (IL) gating on magnetic thin films withabundantelectronic, chemical and magnetic interactions at the interface has become an emerging technology for controlling magnetism in a fast, compact and energy-efficient way. Compared with conventional strain effectdominated piezo/ferroelectric layer multiferroics, IL gating method has advantages like small gating voltage (Vg<5 V), easy-to-integration and compatibility with varied substrates such as Si, flexible substrates etc. Inadditional, unlike the oxide structures require a high temperature to overcome the oxidation energy barrier, the IL gating control process can be operated at room temperature, suitable for applications in room temperature environment. Here, we will summarize our recent progresses of IL gating control of magnetism in varied magnetic heterostructures, as well as in dfferent manners.[1-5]As IL gating process, proven to be a truly powerful and compatible gating method, enables giant ME tunability in different heterostructures and provides a tremendous potential in next generation of voltage-tunable spintronics/electronics.
