Recent breakthroughs in material discoveries and spin-orbit torque control of vdW ferromagnets have opened a path for integration of vdW magnets in commercial spintronic devices. However, a solution for field-free electric control of perpendicular magnetic anisotropy (PMA) vdW magnets at room temperatures, essential for building compact and thermally stable spintronic devices, is still missing. Here, we report a solution for the field-free, deterministic, and nonvolatile switching of a PMA vdW ferromagnet, Fe<inf>3</inf>GaTe<inf>2</inf>, above room temperature (up to 320 K). We use the unconventional out-of-plane anti-damping torque from an adjacent WTe<inf>2</inf> layer to enable such switching with a low current density of 2.23 × 106 A cm?2. This study exemplifies the efficacy of low-symmetry vdW materials for spin-orbit torque control of vdW ferromagnets and provides an all-vdW solution for the next generation of scalable and energy-efficient spintronic devices.Energy EfficiencyFerromagnetic MaterialsFerromagnetismRoom TemperatureSpintronicsSuperconducting MaterialsTellurium CompoundsTorqueTorque ControlTungsten CompoundsVan Der Waals ForcesDeterministicsElectric ControlEnergy EfficientFerromagnetsHigh Density EnergyPerpendicular Magnetic AnisotropySpin OrbitsSpintronics DeviceTwo-dimensionalVan Der WaalMagnetic AnisotropyAnisotropyArticleCurrent DensityMagnetOrbit ScoreRoom TemperatureTorque[SDGs]SDG7journal article10.1126/sciadv.adk86692-s2.0-85188045630
