Ion‐Modulated All‑Van Der Waals Spin–Orbit Torque Magnetic Tunnel Junctions With Multilevel Switching
Advancing van der Waals (vdW) spintronics requires hardware for multistate storage and in‐memory processing. All‑vdW spin–orbit torque magnetic tunnel junctions (SOT‑MTJs) that simultaneously achieve field‑free operation and multilevel switching have remained elusive. Here, we report an ion‑modulated all‑vdW SOT‑MT...
